I have a male unneutered cat who is 2 years old. He doesn’t whine, fight, spray, breed (entirely indoor and likes it that way) and is the most affectionate cat I’ve encountered. Honestly, I know all there is to know about why I SHOULD neuter my cat so I ask that no one tell me about that, I promise I’ve done my homework. What I haven’t found are any reasons not to and that worries me more than it comforts me. I know there are negative effects to having a major hormone-producing organ surgically removed, but no one will admit to any of them. The only thing I’ve heard is that cats may gain weight after being neutered because they won’t be spending as much energy on humping and fighting and their personalities may change…they’ll be more friendly. Yay. Those are backhanded answers. When a human goes in for any surgery there is a 3 page handout that covers all of the possible side-effects even for tonsilechtomies. All I want is similar information for my cat so I can be fully informed.

  • Reasons to castrate cats/dogs are static baseless, environmental impact scientific study-less, specious type endangering/protecting clue-less. Stop interfering with nature we always mess it up till it’s too late to repent.

  • Humbly, I try to keep the many factors in perspective. I think the pros and cons are different for indoor and outdoor cats

    from what I have been reading, with outdoor cats there are some possible benefits, one being they will be less likely to get wounds from being in cats fights defending their territory. Also, neutering will keep some control on kitten pop.

    with Indoor cats – that have no contact with outdoor cats through windows ( basement windows etc ) they will less likely need to be neutered. if they remain indoor cats, being indoors will have the same affect on the kitten pop as being neutered.
    If they do have contact, albeit through windows they probably will get a stronger urge for mating and may spray. So neutering may need to be done.

    HOWEVER

    Dont kid your self about cats won’t care about what has been done to them, Cats DO know and DO remember when there balls have been cut off (castrated) or claws being surgically removed . My moms cat was very affectionate and playful and because the vet said that all cats have to be neutered and declawed, she blindly had it done. HOWEVER, after neutering and declawing this kitten of 6 months, completely changed and I mean completely. It refused to be affectionate to my mom for years and lost its playfulness. I got the cat as pet for my mom and after that event, it was no longer much of pet other than feeding it and changing the litter box.

    objectively speaking, every case is different.

  • Are you joking? Don’t neuter a cat? Do you like having the stench of cat spray all over your house? DO you believe that cats should just remain unneutered thus allowing them to just reproduce and create hundreds of cats? Just think of a household of four cats, two male, two female. The females each give birth to five kittens, by the time those kittens are about 8 months old, they will be creating more kittens, another 6 to 8 months there will be more, etc.

    Explain you YOU will prevent the multiplication of cats. I guess you have never seen news on TV where a home of, often an elderly person, has a couple hundred cats and the walls are covered with cat sh*t and the house smells terrible.

    • Explain how your ability to do basic math and give non-specific examples without citation makes your opinion worth the ten seconds it took to read it. Explain what gives you any authority to speak on the matter as if credible. Explain how you will prevent the multiplication of idiots such as yourself. Or are we too late for that?

  • Its absolutely a terrible thing to do. I dont like how when someone questions weather its right or wrong everyone enforces u to think it should be done by scaring u and telling u the bad things that will happen if u dont do it. Just ask yourself if u would do it to urself or your kids. If u wuld then do it to ur cat. If u wuldnt then dont do it to ur cat. There is also a large human population, male humans fight for females, male humans go looking for girls. So does that mean we should be nuetered as well? No because its cruel and inhumane and un-Godlike. So please dont do it to ur cat for ANY reason.

  • 4 months is honestly too early to neuter a cat, no matter what a vet says. This will definitely cause them to not develop properly. They really should hit their puberty before fixing them. At around 6 to 8 months once you notice their urine change smell, it’s time to do it. After the urine changes so will their behavior. If you have an outdoor cat then you must do it for their safety. It not only helps with over-population, but reduces their chances for territorial disputes and catching diseases. I’ve had a cat die from Feline Leukemia and its not pleasant. For an indoor cat, you might get lucky avoiding neutering. If they don’t spray, whine or act agressive then leave matters alone. However, if you have a multiple cat household its really likely they will spray and get into fights. The cons of neutering could be laziness or timid behavior, but the pros definitely outweigh the cons. I’ve had many male cats, all neutered at 6+ months and they lived long lives. Feed them a proper raw diet as cats need (no store bought canned or dry food ever since its pure poison) and you’ll have a very happy and healthy friend.

  • I am struggling with the decision to have him done or not have him done at the moment. My cat, Oscar, was only about 4 weeks old when he wandered into a friend’s garden in Spain. They had four large rescue dogs that didn’t like cats and so needed to home him. He had already injured his tail or maybe he was born with a break in it but the vet had a look and said it was fine. He clearly has some Siamese in him with the typical colour points and blue eyes. He is now 14 months old and has already had some traumas. At around 8 months he came in from the garden literally screaming and it transpired he had dislocated his jaw. At the time he did this, and I have no idea how he did it, I wa thinking about having him snipped. Because of the trauma of this I delayed it. Until the last month there have been no problems but this last month has been a nightmare. Firstly he lost a small patch of fur at the top of his thigh near the base of his tail. I had a look at it but there didn’t really seem to be anything to explain the cause. He began to lick it constantly and an infection developed. It bled constantly and the vet said that he had been bitten. On shaving the fur the bite marks were clear and I had to pump 2 parts water and 2 parts peroxide into the wound that had become infected. You can imagine the joy of that – not. After a couple of weeks it healed and everything is fine in that area. However, this last week he has spent the whole time calling in a very loud voice with the Siamese yowl at its best. At the beginning of the week he came in with what looked like an infected eye that he hadn’t got when he went out. His eye has been scratched and I am treating it with eye drops. One of the problems here is that there are some really big bruiser cats in our area and Oscar is not very big. I am in two minds about the op because after one of my male dogs had the op he became more aggressive rather than less. Any advice will be gratefully received. I am not sure whether toms go through phases of calling but a week of it has driven me and the neighbours mad!!!!

    • I have cats my entire life. At this very moment I have 3 males and 3 females. One male is not neutered , yet. i am debating myself whether to do it or not. He is 8 months old now. I did notice his behavior changed. He is becoming a macho cat. No spraying, yet, but i guess that doesn’t start until 18 months old. I had many males neutered and not and every cat is different. Not neutered cats were all outside cats and never sprayed inside of my house, except the last cat I’ve got. he was about 4 years old and he sprayed inside, so I had to fix him. Before neutering he was a macho cat, fighting with all stray cats, coming home like from a World War 2! After being neutered he continues to fight, but doesn’t spray anywhere. But he became skittish. He never was afraid of anything before, but after he is just so skittish that it’s like a different cat. With my kitten I want to wait for his full development, since I have read that liver and kidney must be developed to be able to go through anesthesia, to avoid serious complications. Plus his muscular development will be so much better with testosterone being present. So, I am waiting until he turns a year old.

  • Our cat Cicero had this problem, too. My advice would be to get in a closed room, by yourself or with your husband, and just spend time with the cat. After a week of that, go up to having a friend come in the room, with you, instead. Slowly get your cat to acclimate to your friend… If you have another friend that would be willing to help, after a week, I would switch… this worked with our cat, as he now comes out of hiding… before he wasn’t at all.

  • i HAD MY CAT NEUTERED AND HE HIDES ALL THE TIME WHENEVER WE HAVE PEOPLE OVER. HE USED TO BE VERY FRIENDLY BEFORE NEUTERING HIM. THE ONLY PEOPLE HE LIKES IS ME AND MY HUSBAND, HE GETS FRIGHTENED FROM EVERY LITTLE NOISE INCLUDING THE DOOR BELL. HAS BEEN MORE THAN A YEAR AND HE WAS 4 MONTH OLD WHEN HE WAS NEUTERED. I HAVE NO IDEA WHY THIS HAPPENED, BUT IF ANYONE HAS ANY FEEDBACK PLEASE SHARE. I LOVE MY CAT AND I HATE SEEING HIM LIKE THIS. HE IS WASTING HIS LIFE HIDING. HELP???

  • Hi i know that everyone says yet your cats neutured or spayed but to be honest the more the cats and kitten population goes down the more chanse there is of the black plauge coming back I have a 2 year old male thats about to be neutured and thats only because he ran away for a year and he came back 3 days ago

    • why? do you mean bcoz they eat mouse?if so you gave me a great argument against some fools who argue that if we want to feed the neighborhood cats we should take them all in our house .o thank you for that ,the question however is if thats healty for the cats

  • I have cancelled my 6 month old boy’s surgery once already and I am lying in bed tonight a nervous wreck because he is once again scheduled for neutering in the morning. My husband has told me that for me to have this done is cruel and inhuman. My mother died 2 months ago and I have been caring for my father since. I found this little one at 5-6 weeks old living under the shrubs at a hotel, catching lizards and insects to live on. I could see every bone in his tail he was so starved. He had survived cars and huge trucks whizzing past and heavy booted highway workers stomping past him. No way could I leave him there, he had such a will to live.

    Two years ago we adopted 2 wonderful shelter cats that were neutered and my husband will never stop going on about how cruel the shelter was to do this to them. Now, it’ll be me that’s cruel. These are strictly inside cats that have their claws and now they’ll have a little brother. I am 2 states away and on my own. I will never hear the end of this. It’s going to be a long night.

  • My cat was about 9 before I had him neutered. I struggled with it as I felt it wouldn’t be fair on him and that it wasn’t needed. However in the end it felt cruel not to as there were numerous fights he was getting in to which had health consequences. He had his eye scratched and was very lucky that it managed to heal on its own with medication but this was an ordeal for him and very stressful. He began over grooming and lost lots of hair. There have been other times were he has come in with scratches and so on. In the hope his health would be better protected I had him neutered. We tried to keep him in more but cats are independant. our neighbourhood isnt a very big one and i barely see any other cats but my cat just seemed to be unlucky. Since this has happened there has not even been one occasion that he has come home cut or hurt. He seems happier and looks a lot healthier. He is very affectionate and I believe it was the best thing for him… Not for fear of him breeding or spraying but for his health!

  • I had a hard time adjusting from a beach town in Danang to a large polluted city in Hanoi. Hanoian men also like to eat cat meat with vodka. That alone made me get him ‘done’. I don’t want to lose him that way. If he dies fighting or the other one 😉 no problem, but getting knifed/strangled by a local would really get to me.

    He hasn’t been spraying inside at all, but as soon as we got to Hanoi the cries at the door all night also got to me as I couldn’t let him out there.

    Believe you me, there is no ‘overpopulation’ of cats over here.

  • Well, neutering cats (from what I’ve experienced) just makes them a lot more lazy for awhile, and they might not eat or make as much as usual following the surgery. He may do worse if he gets infected following the surgery, which is absolutely possible. However, I would still recommend you neuter your cat, just to be safe because worse things can happen if you DON’T neuter him.

  • My Tom Cat is more than six years old… Sprays, roams, always wants to run away, etc… Is he too old for neutering? Some people say he won’t stop urinating all my apartment after neutering. What do you suggest? 🙁

  • I have been through this dilemma…but today I decided to have my tom cat neutered. He was roaming,getting into fights over territory.He returned home well and just as loving as ever. Perhaps in your case,if yours is an indoor cat then he wont be at such a risk as outdoor cats.However,my kitten is only 10 months old,and I had noticed he was giving off a more pungent smell in the home. when I HEARD OF the over population and unwanted kittens in the world…isnt that cruelty?

  • i forget the details but i did hear that there are certain cancers and or health concerns that are more probable with nutering your cat. I too have ethical and health concerns for my kitty, people say oh he wont know the difference hes just a cat, it doesnt matter to him. but how do we know this? because he doesnt jump up and say “hey gimme my balls back” cats can suffer from deppression just as much as humans, and i can certainly see this being a possible reason.

  • Aside from the reasons you mentioned above (breeding, fighting, spraying, roaming, etc.), a big plus I see to having your indoor male cat neutered is the smell. Tom cat urine stinks to high heaven, I don’t know how you tolerate it indoors. I worked in a vet clinic for 2+ years, and dealt with all kinds of smells, but tom cat urine clears the room every time. We’d literally have to air the place out if we had a tom cat hospitalized. We’d empty his litter pan immediately after he used it and take the litter outside, but the entire office would stink. The only smell I ever encountered wose than tom cat is Parvo in dogs, and I wouldn’t wish that on anyone either. If your unneutered cat isn’t stinking up your house, I wonder if he has some sort of problem–perhaps undescended/underdeveloped testicles that are not producing enough hormones to cause the odor.

  • i;ve never seen negative things happen to a cat ;after it was neutered or spayed;.the cats that i seen including my 3are the same except that they won;t be having litters every 4months…they are not fat and lazy either..one thing is different ;that they don;t stand at the door ;and wine and cry 24/7,,there all the same even more happy now,,,,

  • No negatives, all positives. They are healthier and live longer when they are neutered. Weigh gain can be controled with diet, so don’t let that stop you. I have a neutered Mainecoon who is 8 years old. He is active and a very happy cat and not overweight. He never runs off, even if the goes outside for a breath of fresh air, he has no reason to seek out the female cats in heat. So we have helped with the “unwanted cat” population. I truly believe in spaying and neutering. I hope this helps.

  • Since your cat is indoors only and is not exhibiting typical unneutered male behavior, I see no particular reason to put him under the knife.

    That being said, I’ve never noticed any particular changes in male cats after they’ve been fixed, other than weight gain, sluggishness, and the elimination of some behavioral problems (namely aggression, wanderlust, and spraying). If there are other changes, I haven’t noticed them.

    Since your cat is two years old and has undergone puberty already, any changes brought on by neutering would be particularly minimal. This is one reason vets opt to neuter pets while they are still kittens or puppies.

    This site lists some pros and cons, if you’re interested: http://www.petplace.com/cats/pros-and-cons-of-spaying-and-neutering-in-cats/page1.aspx

  • I don’t know about the negative effects… as I am like you… I did not do it… because I would not like it done to me.

    Unlike you… my cat goes outside… spray and fight. He does not spray inside… only outside.

    The reason that yours does not spray is because he has not come into contact with another cat. If he could smell another cat outside your house or flat… he would start spraying to establish his territory.

    What I know is that the main reason people neuter their cat is to stop them spraying. What I also know is that unless you neuter them at an early age before they get into fights… it won’t work anymore. Once they developed the taste for fighting… they will keep on fighting after they are neutered.

    What I don’t understand… is why anyone would want to buy a male cat… and then neuter him. It seem to defeat the logic.

  • Sounds like to me that if your cat is happy and you don’t have any reason to do so,Why do it then.I have a dog thats indoors and not neutered and hes like 11 yrs old.Had a cat that is 7 yrs old had him neutered cause he was always roaming .He now is happy to stay right around the house and have not had any health issues ever.So, guess it’s your choice.Hope you make the best one for everyone.

  • Sounds to me like you’ve done your homework! Honestly if you’re fine with keeping all his “parts” then do so – but ONLY if there is no threat of him getting loose and increasing the cat population. I work as a volunteer taking care of cats and kittens that need homes with loving people and it breaks my heart each time a kid is dropped off because of the over-population. So please – if there is a chance of your little boy getting loose, don’t risk it – have him neutered to keep the pet population down. Your one little snip may not seem like much, but it really is! God bless you for checking so thoroughly too! You sound like the kind of owner that many cats need to find more often!! 🙂

  • I think the main drawback is usually the weight gain, and sometimes a neutered male will also have urinary problems. I would say that if you have none of the usual problems with your un-neutered male, then don’t have him neutered. The only thing would be if he were to get out, he could end up in a fight, as well as possibly fathering more unwanted kittens. Good luck to you.
