My vet sexed my cat to be a boy and she had kittens?
Is this usual?
I'd get another vet.
Only on rare occasions do humans ever have kitten offspring.
Not that unusual. When they're really young it can be hard to tell, even for a professional.

If it was an adult cat, then yes, I would say it was unusual. Still, you should have brought him in to be neutered, and they would have figured it out and spayed her.

Good luck with the kittens.
Get another vet fast it takes 20 seconds to tell between a boy or girl kitten even a newborn.

Yes, that is unusual. You should find another vet.
any person with a brain, and especially a college DEGREE can tell a boy cat from a girl for God's sake. get another vet asap!!
I'm not a vet but I can tell by looking whether a kitten or a cat is a male or a female. If a vet can't do that, then I definitely would recommend finding another one.
