Hi I am new to the forum and really need some help. My 10 week old kitten, Rick, has stopped eating and is not active like he was up until 2 days ago. He threw up some spit also today. He was always a good eater and very active with my other 3 cats (they are older). He has also NOT been urinating in the litter box, only on other things. Does anyone have any advice on what is wrong with him? He is getting really thin also.
