Hi I have a 4 yr old male inside onlycat.. I fed him nibble the first three yrs of life.now he's on fancy feast.. But he vomits 3 or4 times a week... At first on canned he got better no vomiting.. He was born with herpes. I give him llysine twice a day for herpes symptoms. But the vomiting worries me... He's on cat lax too.. I'm worried it may be serious or just sensitve stomach any advice would help! I lost his sister in April to a hairballs blockage..

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Sophie! Since Sophie is young I would make sure she is properly dewormed. It would be a good idea to submit a fecal sample as well, but I would deworm her even if she is negative. Vomiting, not just diarrhea, in a young cat can be from intestinal parasites. If the vomiting continues then I would play with her diet. Try to stick with one flavor of fancy feast for a period of time to see if the vomit stays the same or improves. You may have to change brands. Food allergies or intolerance commonly causes vomiting in cats. Vomiting 3-4 times per week is too much, "normal" vomiting for cats is once every 3 months. If the above doesn't work I would have a physical done by your Vet and see if she is losing weight or is too thin. I hope this helps and I wish you and Sophie the best!
