My cat had 4 kittens yesterday morning... ( they are her first and only litter and all kittens are going to family) she is being a very good mom but she hasn't been to the toilet yet... She is eating but only when I put the food right by her... She will not leave the kittens not even to eat or drink... She is fine... Fussy and loveing being a mommy... She as got a litter try... Food and watter right by her... It's been 33 hours now and I'm starting to worry a little...

Don't worry, she can handle this. She knows what has to be done. It isn't a health related problem it is her caring for offspring, as you said.
