It is important that you feed your pet a food that is highly palatable and tempts your cat to eat. Royal Canin Veterinary Diet - Renal with Tuna is an energy-dense wet cat food, especially formulated for pets with kidney failure. Even a small portion of this food provides your pet with the energy it needs. This complete wet food supports kidney function in cats with chronic or temporary renal insufficiency, and is ideal for use in combination with Royal Canin Veterinary Diet - Renal RF 23 dry cat food. It has a low phosphorus content and contains top-quality proteins, which can help to prevent the occurrence of urate, cystine and calcium oxalate stones in susceptible cats. The antioxidant complex in this dry food also supports cell protection and your cat's immune defenses. Key benefits: Low phosphorus content: Renal failure means that your cat's kidneys can no longer eliminate phosphorus properly. Limiting the dietary intake of phosphorus can support renal function and help prevent secondary hyperparathyroidism, which can lead to chronic renal failure. EPA/DHA: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are long-chain omega-3 fatty acids, which can have an anti-inflammatory effect, helping to improve glomerular filtration. Digestive system: Advanced uremia can result in gastro-intestinal ulcers. The combination of fermentable fibres (FOS) with zeolite helps to promote a balanced gut flora and support the health of your cat's intestinal mucosa. Antioxidant complex: Synergistic complex of antioxidants (vitamin E, vitamin C, taurine and lutein), which helps to protect the cells against against free radicals. It also supports the body's immune system and can prevent cells from premature aging. Changing your pet's diet and length of treatment: If your pet suffers from chronic kidney disease, it may be necessary to feed your cat Royal Canin Veterinary Diet - Renal with Tuna for the rest of its life. The earlier you start feeding your cat a specialist diet, the more effective it will be.
