Best Cat Food for Kidney Disease Buying Guide & FAQ
How Protein Restriction Impacts Your Cat's Healthy Body Condition
A diet with a controlled protein content has a high impact on your feline's body in several ways. Read on to find out.
- Kidney function
Felines are carnivores as such your cat's body can handle a diet with high-quality protein content. However, some felines can't handle meals that are very rich in protein. Foods with high protein levels are harmful to most felines who are experiencing kidney issues because the cats will have difficulties excreting unwanted substances from the surplus protein. When this happens, it makes your cat's kidney work extra or overtime.
- Suitable for older cats
A cat who is well advanced in years is mostly not physically active as compared to younger felines. As such, a matured feline will need a meal with restricted protein content. This because protein gives your cat's body energy; however, as felines grow old, they require controlled protein in their meals as they do not burn off sufficient energy. Thus, excess or high protein may harm your cat's kidneys. Therefore, consult your vet to prescribe a controlled protein diet once your feline starts aging.
- Reduces the amount of phosphorus and Urea
A diet that is rich in protein increases the content of phosphorus and urea that your cat’s body requires. A meal with high phosphorus levels will harm and damage your cat’s kidney.
Benefits of Renal Diet for Cats
Renal diet for felines is crucial because it helps to slow down renal disease among cats, and also uremic issues or episodes are prevented when cats are put on renal diets. Moreover, the renal diet helps to prolong your cat’s lifespan. Again, the renal diet contains restricted sodium, phosphorus, and protein. A meal with high phosphorus content increases the chances of your cat developing renal disorders or failures. In contrast, a controlled phosphorus diet reduces the chances of renal complications in your cat.
Downsides of Prescription Cat Food for Kidney Disease
When selecting the best cat food for kidney disease, it helps to remember that cats love meals that contain high-quality protein. Felines with kidney issues many a time have low appetites. As such, these cats may be choosy regarding foods that have controlled protein levels. Again, increased intake of quality protein results in your cat having a very lean and healthy body mass, which will end up prolonging your feline's life. Also, since your feline does not have power over his protein metabolic process, your elderly cats especially will break down a vast amount of protein as other cats who are served with high protein meals. That quality protein comes from or is exerted from your cat's muscles, which tends to reduce your feline's lean and healthy body mass. This can reduce your cat's lifespan.
The Importance of Water for Cats with Kidney Disease
Cats who are suffering from kidney disease cannot retain or hold on to water in their bodies. Thus, they need to drink water to avert dehydration. When a feline is dehydrated, the cat's blood becomes thicker, and this is not normal. As such, the flow of blood to the cat's kidney turns to be sluggish, and this causes more damage to the feline’s kidney.
Best Cat Food for Kidney Disease FAQ:
Q: What is a renal diet for cats?
A: A renal diet is a diet that contains less phosphorus, sodium and protein, and high omega-three fatty acids.
Q: When should I start feeding my cat low phosphorus food?
A: You should begin feeding low phosphorus food to your cat when he is suffering from kidney disease. However, you should consult your veterinarian before you commence the feeding.
Q: How to introduce a therapeutic kidney diet to my cat?
A: You should carefully introduce a therapeutic kidney diet to your feline since, at that stage, they may have a low appetite. Begin by making the diet more palatable. Also, if adding extra flavors or textures does not work, you can add appetite or food stimulants such as mirtazapine. If the stimulant is not effective, then you can use feeding tubes such as gastrostomy or esophagostomy tube. This is an appropriate way of providing water, medications in liquid forms, and food to felines with kidney disease.
