My skinny male kitten yowls at night. Is he sick or just unneutered?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | unneutered | 8 lbs

My kitten is a little on the thinner side and meows quite a bit, and yowls at night..he is a male and isn't neutered. My kitty also was weened off his mothers milk at 5 weeks, could he be skinny because of that? I just worry he is sick, but he is only 7-8 months.

Petey is a very handsome boy! Kittens do start weaning off their mother's milk around five weeks of age, so that is normal and wouldn't likely be a cause of him being skinny. He could be yowling at night because he's intact and sexually mature. He's letting you know he wants to go outside to prowl for females. To stop that behavior, I would have him neutered. Keep in mind as well that intact cats mark their territory with urine, and he could start spraying around the house. That's a very hard smell to get out, and neutering him will stop that. As for being skinny, he may naturally be a thinner cat or he could have intestinal worms. Those would cause him to have trouble gaining weight. I would give him a deworming treatment if he isn't up to date on them, and you can get one from your vet's clinic. I'd also recommend a health check with the vet just to make sure everything is ok with him health wise. I hope this helps :-)
