i just adopted my cat yesterday, and its now the second day and she only used the litter box once, i dont even know if it was pee or poop because i have another cat that used that litter box too. i know you are supposed to keep the two cat seperate for a few days but i have been switching the cats out between my room and the lving area which is rather small anyway. All she does is sleep and shes not motivated to play or anything. shes only a yeat old. my other cat was playing the night we got her this one doesnt seem interested. any way she is also super skinny, and sneezes alot... help!
