Can A Stud Cat Suddenly Become Infertile??

[cindy321]

Our stud cat is 4 years old , he mated with our 2 queens and they both had a litter of kitten last year.

However, this year I have seen him mated with both queens, but none of them get pregnant. And two weeks later, the queen got into heat again, then they mated again, still not pregnant. They repeated this for last 2 months ...

Does that mean our stud suddenly become infertile?

According to this article: https://www.merckvetmanual.com/cat-owners/reproductive-disorders-of-cats/infertility-in-cats, yes, it’s possible for male cats to become infertile. The reason why, can be complex, though, so you’ll need to work with a vet to determine the cause.

C cindy321 - Let me suggest a past thread on TCS, which incorporates a very good answer from @stefanz in the first reply post:

Does your male stud cat spray? Did he ever did and it stopped as well?
