Is This Fat Cat Male or Female?

Question: Is This Fat Cat Male or Female?

Answer: Thanks for the leap of faith, but I can't diagnose the sex of a cat nor its possibility of being pregnant by email.

This stray cat you're feeding could be a neutered male, although there may be some remnant of the testicles sac, depending on the age at neutering.

I guess the question comes down to "what are your intentions with this cat?" If you intend to adopt it, my first advice would be to take it to your veterinarian, who can answer all your questions as well as test the cat to make sure it has no communicable diseases or parasites.

Of course, as you mentioned, it could be getting fat or it could be pregnant. If the latter is the case, it's nipples will become more prominent just prior to birth.
