Why Feed a Cat a Low Protein Diet?

When starting a low protein diet for them, it would be essential to see what type of low protein food they enjoy. Monitoring the amount they ingest is counted as essential to ensure they are eating the correct amounts to maintain their health. Having a vet help with a healthy low protein meal plan for your cat is crucial to ensure their health is being maintained, which can lead to longevity, even with renal failure.

Kidney Functions

The kidneys eliminate protein waste by breaking it down. They maintain a balance between acids, salt, and the cat’s hydration levels. The kidneys also assist in producing urine to dispose of waste products.

Liver Functions

While low protein foods focus on renal failure, it also helps for cats with liver disease. The liver removes by-products of food digestion, absorbs nutrients and produces proteins needed for blood consistency, as well as clotting. The liver also transforms ammonia to urea that is released through urination. Ammonia is a toxin of by-products from the protein metabolism.

By implementing a healthy low protein diet, it reduces the amount of ammonia in the cat’s bloodstream. When there is too much ammonia in the bloodstream, it can cause more severe diseases such as Hepatic Encephalopathy.
