my 12 week old himilayan puked this morning, and he seems to be on the verge of another one . It didnt seem to be a hair ball, it was just yellowish liquid. Ive never seen him do that and i've had him for over 3 weeks. He's on wet recovery kitten food (he wasnt eating when i got him so the vet put him on this food for about a month) Which is also why he put off his shots until he recovers. He also has eye discharge which i assume is from the litter and just a small allergy reaction to the dust (i will buy a new litter once i get the vet's oppinion tomorrow). he seems to be sleeping alot today too. its sunday today so i cant take him to the vet until tomorrow afternoon. I was originally going only to get his shots done but now this is getting me a bit worried. what could be wrong. he was dewormed befor i got him and the breeder said he wont need to be dewarmed again for a month. could it be worms? please help.
