Is my cat's scratching and vomiting due to a food allergy?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | 10 lbs

Does cat have food allergy? Eats merrick chicken limited ingredient wet food; cant have fish (known allergy). After eating the food he will have these scratching fits, seems like skin is irritated, time from time seems like he has throat or mouth discomfort & nose will sometimes look slightly swollen. Also goes at one ear & really digs at it. By next feeding he settles down. But yesterday he didn't seem to want to eat it, had few bites, so gave him plain ground chicken & this AM he vomited it up

Thank you for submitting your question regarding Casper. It is possible that he has a food allergy based on your description. Typically affected cats will have skin lesions, vomiting and/or diarrhea and frequent bowel movements. I recommend that he sees his veterinarian. He may benefit from a prescription diet. Many over-the-counter diets are contaminated with protein sources not listed on the label. A prescription diet will be more pure and could help to alleviate his clinical signs. If food allergies are not to blame, then other causes of his symptoms can be discussed. I hope this information helps!
