Ok, let me just say that I don't agree with keeping cats outside, unless they are ferral & would be miserable inside. That said, I work with a woman who has a brother & sister pair of kittens. They live in her barn, & she had a heated bed for them. Her vet told her in December that the female was pregnant. This woman has never had cats before & apparently wasn't aware that this would happen at 6-7 months of age (I don't know why she didn't ask when she got them) The vet said she'd have the kittens in about 3 weeks, well they haven't come & I personally think if she wasn't pregnant before, she sure is now. So I'm trying to convince her to have the male neutered on the off chance the female isn't pregnant. The vet told her she will have to keep him inside for a while. I figured I'd ask this question here because there are people here who do T.N.R. My question is does he infact have to stay inside & for how long?
