If your cat has been scratching relentlessly, suffering from tummy issues, or exhibiting skin problems, chances are food allergies are responsible. Many cats are sensitive to popular items such as chicken, beef, or grains. That’s where hypoallergenic cat food steps in. It’s specifically formulated to minimize allergic responses, calm upset stomachs, and provide your cat with the comfort it needs.
What Is Hypoallergenic Cat Food?
Hypoallergenic cat food is formulated using ingredients that don’t cause allergies as easily. Rather than utilizing conventional proteins like chicken or beef, it tends to utilize exotic proteins like duck, venison, or rabbit. Certain recipes base their formula on hydrolyzed protein, which is so broken down that your cat’s immune system will never perceive it as an allergen.
In simple terms: it’s easy-to-digest, gentle food designed for cats with sensitive stomachs, scratching skin, or ongoing digestive issues.
Symptoms Your Cat Might Need Hypoallergenic Food
Not every cat requires a special diet, but if your cat has these symptoms, it might be worth a try:
- Ongoing itching, licking, or chewing at their skin
- Red or inflamed areas of skin
- Hair loss or bald patches
- Ongoing vomiting after eating
- Loose stools, gas, or diarrhea
- Ongoing ear or skin infections
These are often symptoms of food sensitivities, and a change to a hypoallergenic diet usually improves them.
Ingredients That Make Cat Food Hypoallergenic
- Novel proteins (duck, rabbit, venison, turkey)
- Limited Ingredient Diets (LID) with fewer ingredients
- Grain-free formulas to exclude corn, wheat, and soy
- Hydrolyzed proteins for more serious allergies
- Added Omega-3s to maintain skin and coat health
- These selections decrease allergic response and support overall health.
