my cat gave birth yesterday. 3 kittens all healthy and feeding well. However I'm not sure if the mothers behaviour is ok. She's not got out of the bed to eat or go to the toilet (tray). I fed her by putting the bowl up to her mouth and she ate a lot. Now it's been about 30hrs since the birth and she's breathing heavily. She isn't panting but her tummy is rising and falling fast. Is this normal? She's licking the kittens and seems to be attentive.
