Is my cat a neutered male or female? What are the visual signs?

Male cats will have a scrotum with two testicles in the scrotum if they are not neutered. If a male cat is neutered they will still have a scrotum but it might be very small and no testicles will be present. If you look under the tail right under the rectum is where the testicles would be located. hope that helps

I think I see testicles in the picture, but I would need to palpate Oscar to be sure if he's neutered or not. I'd make him an appointment with a vet to determine the answer to your question. Until then, keep him away from your female in heat to be safe. Best of luck.

Based on the distance between Comet's anus and genitals, I agree that he appears to be male. The picture is quite blurry when I try to zoom in, but it appears that from the top down, you can see his anus, scrotum, then penile opening (the penis itself is contained inside of this prepuce). I would expect more of a vertical opening for the vulva without anything above it in a female. I've included an article that has a rudimentary drawing that's pretty helpful. This is unrelated, but I also see rice-like particles on Comet's hind end. These appear to be tapeworm segments, which can be acquired by eating either tapeworm infected fleas or rodents. I'd recommend asking Comet's vet about deworming him for tapeworms based on this picture. https://www.petcoach.co/article/sexing-kittens/

The picture is difficult to make out, but it almost looks like a piece of body tissue hanging out. Was he recently neutered? If so I would recommend having a follow up appointment with your veterinarian to see if there is any infection or problem at the neuter site. Good luck and I hope he is back to normal soon.

From this photo, this appears to be a male kitten. You can read more about determining kitten gender at https://www.vetmed.wsu.edu/outreach/Pet-Health-Topics/categories/procedures/cats/determining-gender-(sex)-of-a-kitten

It's hard to say for certain from the pictures, but I think this kitty may be a girl. At a couple months old, you should be able to feel testicles within the scrotum which is under the slit for a penis/vulva. If you can't gently feel testicles, then it's most likely a female, or possibly a male whose testicles did not descend.

I would guess this is a female but it can be a little difficult to tell from a picture. This might help you figure it out at home: https://www.google.com/amp/s/mobile.petcoach.co/amp/article/sexing-kittens
