How to Choose the Best z/d Cat Food Alternative

Food allergies are quite common in cats and have several annoying symptoms. Choosing the right food for your pet can prevent potential allergy issues and help your furry baby recover. Here are a few factors to consider while picking the right formula for your cat.

Wet or Dry

Offering your cat a balanced diet is crucial for the health of the immune system. Wet food can be used to provide cats with the needed hydration, instead of drinking water. Wet food can protect the cat from urinary tract infections as it lowers the concentration of inflammatory components in the urine. However, it usually has lower calorie content, so it might not suit kittens and cats that need more energy.

Dry food is easier to use and can promote better dental health by preventing the formation of plaque. It’s more popular than wet food because it can be left for longer periods, allowing the cats to eat according to their pace, rather than at the specified mealtime.

Here are the top hydrolyzed cat food alternatives to fight food allergies.

Protein Intake

The main ingredient in the cat’s food should be proteins. Popular choices include chicken, turkey, fish, and meat. These will provide the cat with the needed nutrients to promote better digestion and improve the functions of the immune system.

Grains and other protein by-products should be avoided, or consumed in very small amounts, as they can worsen the symptoms of food allergies. They might take a longer time to be absorbed by the stomach and digestive system, increasing the frequency of vomiting and affecting the smell and texture of stool.

Added Nutrients

In most cases, the food you buy for your kitty will be supplemented with other nutrients to protect the cat and improve its health. Omega fatty acids are essential for your cat’s health because they regulate inflammation and promote healthy growth and development. They also improve the condition of the skin and coat, promoting the recovery of the coat after hair loss, a common symptom of food allergies.

Probiotics can also be added to the formula to improve digestion. They will reduce the symptoms of diarrhea and improper digestion.

How to Feed a Cat with a Sensitive Stomach

If your cat always vomits or suffers from diarrhea, you need to choose a special formula that addresses these problems. Here is what you can do to help your furry baby overcome this problem.

  • Talk to your vet. The vet will run several lab tests to rule out any other health issues and make sure that your cat is suffering from food allergies.
  • Start a trial diet by switching to high-quality food that contains no preservatives or fillers. It should also have other nutrients like omega fatty acids and probiotics to improve digestion and reduce the symptoms of food allergy.
  • Pick food formulas with limited protein sources to identify the allergy-causing ingredient. You can also switch to a formula with hydrolyzed protein where the protein particles have been broken too small, so they won’t be recognized by the immune system.
  • Switch the feeding routine. Cats might vomit after eating a large meal, so you can start switching to smaller and more frequent meals.


How do I know that my cat has a food allergy?

There are several symptoms that show that your cat is allergic to food. These include vomiting, diarrhea, continuous scratching, hair loss, excessive gassing, and having red and inflamed skin. If your cat has these symptoms, you should take them to the vet to see what’s wrong.

Can cats develop food allergies at any age?

Yes, they can. Some cats are allergic to a certain type of food since birth. However, other environmental factors like stress can cause an allergy to a specific type of food.
