Is this normal? What can we do to help through this and how long will it last? The kittens left at 10 weeks and momma cat has been going in their room crying/meowing and sniffing around a lot. She is barely eating and lethargic. It's only been one day, but should I be worried? The vet said they are usually ready and "sick of" their kittens by this time, but she looks devasted! Any of your expereince or wisdom welcomed. Thanks.
