So how do you know whether your cat is experiencing an illness or an allergy?
The most common way an allergy manifests in cats is itching, irritated skin.
Another way an allergy might show up incatsis through digestive upset resulting in vomiting or diarrhea.

This could include beef, chicken, fish, etc.
It could also include vegetable proteins like those in wheat or corn.
Allergies could also result from food additives or preservatives.

The most common allergy in cats, however, has nothing to do food.
Rather, your cat likely suffers from the most common cat allergy: a flea allergy.
It only takes a single flea bite to create this level of discomfort for a cat that is allergic.

There are a few ways to do this (viaWebMD).
Similarly, washing any pet beds weekly will prevent similar issues.
These treatments include products like Frontline and Advantage.
