I was just reading another LOOOONG thread about a cat that took forever to have kittens and it was exactly the same situation and the kittens came out fine. It was just a matter of them getting the dates wrong on the breeding or whatever. I hate to say this but I don't have the money for an oxytocin shot and the only vet open is an emergency vet. If she NEEDS it I can find the money but since she seems okay and things seem to be progressing at their own rate, I don't think I need to interfer with what's happening.
Today was the first day she got in the crate, nested around, and stayed there. I think we are very close. She has been having normal stools for days and suddenly today she had a loose one. I don't think she's eaten today either. It all sounds like labor to me.
