I just adopted 2 kittens from the humane society. They are both about 9 weeks old and have been at the humane society since they were about 4-5 weeks. They were abonded byu there owner and left in a bag on the side of the road, I don't know how much time they really had with there mother. One of them is doing great; eating, using the litter box and playing. The other kitten will not use the litter box and hardly eats anything, she cries alot also. I think she cries just to be fussy though. When I adopted them they said they both had upper respitory infections and gave me medicine for them. I dont know what to do about the fussy kitten. She is very skinny but doesnt really eat. I bought wet kitten food and she will only eat about half a can all day. I figured she would pick up the litter box thing from the kitten but she hasnt used it at all. I tried putting her in it after she pees on the floor and stuff but she just wont use it. Anyone have a thought as to what to do?
