Maybe she just needs some extra coaxing ! If not, call your Vet when you can !
Hello. My cat gave birth today in the morning, but she only had 1. Is that fine or not. Please help?
It's not typical...
It's not usual so if she looks as though she's straining or you can still feel her tummy is lumpy then get her to the vet ASAP. She could have more kittens in there and after this I hope you'll get her spayed.
