Has anyone had a cat that has had a small hernia .. congenital I think .. it was supposed to be taken care of when our Lucy was spayed and front claws done .. she is 5 now and lately she has been throwing up a bit at night for the last 2 weeks .. I thought it was a furball problem .. bought the grease in a tube (she won't even give it a try) and the Purina cat chow for furballs .. she does like that. I'm really just looking for anyone with experience with this in their cat .. I'm making an appointment for her with our vet this week ... just to make sure she isn't in danger with this .. they said it was not a problem before. Any input much appreciated ! Fudge : ) PS .. our cats are totally indoor cats.
