As a cat owner, you may have heard of cat food with hydrolyzed protein while looking for the best diet options to keep your cat healthy.

So what is it?

Hydrolyzed protein is when certain proteins are broken down into smaller components using the process of hydrolysis.

Okay, but what does this have to do with cat food?

What Does Hydrolysis Mean In Hydrolyzed Protein Cat Food?

The process of hydrolysis involves adding water to the protein molecule and breaking the chemical bonds that hold the molecule together. This results in the creation of smaller peptides that are more easily digested by animals, including cats.

Hydrolyzed protein is often used in cat food as a source of protein, especially for cats with food allergies or sensitivities.

Because the protein has been broken down into smaller peptides, it is it is easier to digest and less likely to cause an allergic reaction in cats, who are sensitive to certain types of protein.

In terms of cats specifically, feeding hydrolyzed proteins can help them feel full faster, support their cardiovascular system, and provide relief if they have food sensitivities or allergies.

Hydrolyzed protein can be derived from a variety of sources, including meat, poultry, and fish.

It is important to carefully read the ingredient list on cat food labels to determine the source of the hydrolyzed protein and to ensure that it is appropriate for your cat’s needs and dietary restrictions.

Hydrolysed protein is an important part of a balanced cat diet and all cats can benefit from it.


Which Cats Will Benefit From Hydrolyzed Protein?

Cats that have special dietary needs may find that hydrolysed protein is especially beneficial.

Senior cats with sensitive digestion systems or skin issues are likely to benefit from hydrolyzed proteins as they provide nutrients while avoiding further irritation.

Kittens and older cats that lack the digestive enzyme necessary to break down larger proteins are also good candidates for this type of food source. 

Cats suffering from food allergies or kittens recovering from surgery are just some of the groups who may experience the particular advantages of this type of diet.

Hydrolysed proteins are partially broken down prior to the production of cat food so that they are more easily digested by cats with health concerns.

In addition, hydrolyzed proteins are more likely to be hypoallergenic than other proteins because they eliminate large peptide molecules, which can trigger allergic reactions.

Which Brands Of Cat Food Offer Hydrolyzed Protein?

There are several brands of cat food that offer hydrolyzed protein. Some examples include:

Royal Canin: This brand offers a line of hypoallergenic cat food that is formulated with hydrolyzed soy protein to minimize the risk of allergic reactions. This is dry cat food.

Purina Pro Plan: This brand offers a line of cat food formulated with hydrolyzed protein, including both wet and dry options.

Always check with your vet before embarking on a new diet regime, particularly if your cat has health concerns.

How To Transition A Cat To Eat Hydrolyzed Protein Cat Food

If you are considering transitioning your cat to a cat food that contains hydrolyzed protein, it is important to do so slowly and gradually to give your cat time to adjust to the new diet.

Here are some steps you can follow to transition your cat to hydrolyzed protein cat food:

A 7-day plan transition plan is suggested.

On the first and second days, mix 75% of the old food with 25% of the new food and serve it in a separate bowl from the old food. Cats may not accept mixed diets, so it is recommended to keep the old and new food separate.

On the third and fourth days, mix 50% of the old food with 50% of the new food.

On the fifth and sixth days, use a mixture of 25% old food and 75% new food.

On the seventh day, you can give your pet only the new food.

Observe your cat’s appetite and behavior during the transition. If they seem to be eating the new food without any problems, you can continue increasing the amount of new food and decreasing the amount of old food.

If your cat refuses to eat the new food or has digestive issues or allergy symptoms, you may need to go more slowly or consider switching to a different brand or formula of hydrolyzed protein cat food.

Offer small, frequent meals during the transition period to help your cat adjust to the new diet.

Consult with a veterinarian if you have any concerns about your cat’s diet or if you notice any changes in your cat’s health during the transition.

It is important to be patient and allow your cat time to adjust to the new diet.

If A Kitten Starts Eating Hydrolyzed Protein Do They Have To Always Eat Hydrolyzed Protein Cat Food?

It is generally safe for kittens to eat hydrolyzed protein cat food as a source of nutrition. Hydrolyzed protein can be a good option for kittens with food allergies or sensitivities, as it is less likely to cause an allergic reaction than other protein sources.

Kittens have different nutritional needs than adult cats and may require a different balance of nutrients in their diet.

It is generally recommended that kittens be fed a diet specifically formulated for growth and development.

These diets are formulated to meet the higher protein and nutrient requirements of growing kittens.
