Overview on Hydrolyzed Protein Diets for Cats
- Hydrolyzed protein diets for cats are being overprescribed.
- The science behind these diets is unproven and may have long-term side effects.
- Studies suggest that some cats still react to hydrolyzed proteins.
- It will be healthier to test or identify and eliminate the problematic protein rather than rely on ultra-processed diets.
The Misconception of Hydrolyzed Protein Diets for Cats
Hydrolyzed protein diets are often prescribed for cats experiencing sensitivities, especially skin or digestive issues. These diets are thought to chemically break down proteins to prevent allergic reactions, but there is a significant gap in the science supporting their effectiveness.
According to a publication in Pub Med Central, “the potential of these diets to stimulate lymphocyte-mediated hypersensitivity is currently unknown.” In other words, the long-term safety and efficacy of these diets remain unclear. Feeding a hydrolyzed diet to your cat may come with unintended side effects, especially if it is used as a long-term solution.
A 2017 study by Kathrani et al. discovered that some cats, despite being fed hydrolyzed diets, still experienced similar allergic reactions to those they had when consuming whole proteins. This raises an important question: if a hydrolyzed diet doesn’t solve the issue for all cats, could there be a better approach?
The Problem with Long-Term Use
Hydrolyzed diets are highly processed, and obligate carnivores like cats thrive on whole, fresh meats. Long-term feeding of chemically modified proteins can deprive them of essential nutrients found in whole, natural meats. This could eventually lead to other health complications.
While hydrolyzed protein diets are sometimes recommended for short-term use, they should not be seen as a permanent fix. If the issue lies with a protein, why not eliminate the suspected protein and replace it with another unaltered protein?
A More Natural Approach
Fresh, whole meat options—such as novel proteins that your cat has never eaten before—are often healthier alternatives and can resolve the confusion as to if the symptoms your cat is experiencing is, indeed, due to the protein they are eating. These meats provide cats with the essential nutrients they need without the risks associated with processed foods. By switching to a more natural diet, you’re not only addressing the underlying issue but also promoting overall health.
The next time your cat has a sensitivity, try switching their current diet or consider testing for sensitivities rather than guessing. Eliminating the suspect protein and observing how your cat reacts might even give you the answer you seek. By playing the elimination game or testing first, you’re supporting your cat’s health without resorting to highly processed foods.
