I have a cat that is almost three years old and the past few days he hasn't been acting himself. At first he wasn't eating or leaving the house, he was just laying around. Last night he finally went back outside and he has been eating all day long. I picked him up yesterday and some light yellowish liquid came out of his butt. Then again tonight, he was sitting on the floor and when he got up there was a spot of clear liquid with some type of mucus in it. I cannot pick him up because every time I do more clear liquid comes out. Does anyone know what this might mean?
