My cat just had a litter of 3 kittens last weekend and they all died, they seemed to be a little premature when they were born, and now my cat won't eat and has been sleeping almost three days now other than going to the restroom. She is only a year old and I found her on the street at a gas station about 2 monthes ago, I don't know what to do with her now that she is acting as if she's sick or depressed or something, she seems to be also having a hard time keeping her balance at times.
