My new kitten, just about 2 months old that I found outside in the garbage is spending alot of time in the litter box, just sitting there. She just really started eating yesterday when I mixed her wet food with dry, but I haven't seen any new poop in about a day now and I am concerned because she is just sitting there. She is drinking water and peeing alot. She is very thin and I just found her thursday. Does anyone have any suggestions?
