Q. My female cat throws up alot after eating cat food, my male has now started doing the same thing. Happens when they come inside.

Answered By

A. It is possible your cats may have an internal parasite causing them digestive distress, or they may have an allergy to an ingredient in the food (wheat, corn and soy are the most common). It is a good idea to bring in fecal samples to your vet to rule out the most common causes of vomiting and diarrhea, and then to check your food for common allergenic ingredients. A diet change or treatment of the underlying cause may help.
