Hypoallergenic Cat Food: Which are Best? (5 Varieties Reviewed)

​Allergic reactions have traditionally been associated with human beings.

However, a recent study indicates that the number of allergies is on the rise, and not in humans alone, but also in cats.

Allergic reactions on cats are manifested several ways including excessive scratching, dermatitis and extreme hair loss.

Though skin responses are the most common reaction to allergies in cats, allergic reactions can also result in vomiting and diarrhea.

If your cat is experiencing allergic reactions, there is a good chance that a change in diet can help reverse the effects.

Ideally, cat parents recommend switching to a hypoallergenic cat food since this diet is prepared without ingredients that could potentially trigger allergic reactions in cats.
