Can a healthy cat eat Royal Canin renal food if they don't have kidney disease?
Yes, it is ok to eat renal food, but only as a treat or supplement to the main diet of Hills Rx Senior. Renal food is lower in protein than normal cat food since the kidneys can't handle excess protein when they are failing. So it would be best for long-term health if Tony gets plenty of protein, which is in the senior diet!

Cat with kidney issues: Best food brands & Milk Thistle advice?
Many cats with renal disease get picky with food so you may end up trying all the brands at some point or alternating between them. You need to feed Mercy a prescription diet for the renal disease. The brand Royal Canin tends to be the most palatable. They make 3 varieties of kibble and 3 varieties of canned food that are all for renal disease. They have different smells/textures...etc so just pick a bag (or all 3) and try it. You will need to ask your normal veterinarian about continuing the milk thistle. The renal diets are lower in protein, higher in fat and higher in fatty acids/antioxidants and this can be beneficial for the liver depending on the cause of liver elevations. Your normal vet will best advise you. I hope this helps and please feel free to post any additional questions.

Fussy cat with kidney disease won't eat vet food. Best store wet food?
We always say that it doesn't matter how good a food is if the pet won't eat it. This is especially true with cats. Your goal with a diet for a kidney patient is to avoid foods that are too high in protein, so you will want to avoid any kitten foods. Most non-prescription diets are very similar in their protein levels because they are made for the needs of an average adult cat. If Cricket was previously on a dry food, I found the best way to get my cat to eat canned food was to grind up dry food, then sprinkle it on the top of his canned food to get him eating. I am attaching a link to a handout below with tips to transition a cat onto canned food. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=3041 Since Cricket has been a fussy eater, the most important thing will be to find a food that she likes. I have found that cats tend to like Fancy Feast the best, so that might be an option if you can't find something else that she will eat. Good luck! I hope that was helpful. Thanks for using PetCoach.

Cat with kidney failure: Can I mix RX food with organic & supplement?
Prescription kidney diets have proven to improve both quality and length of life in pets with poor kidney function. They are formulated to reduce the amount of work required for the kidneys by reducing the amount of waste products produced from food as well as containing tightly balanced mineral, vitamin, omega fatty acid and protein levels and work best in wet forms or where good water intake can be encouraged. The larger proportion of the diet the better, any additional food sources should be highly digestible and suitable for pets in kidney failure, blood tests would be recommended 3-4 weeks after any diet changes to ensure no negative impacts develop

My cat has kidney issues. Is vet-prescribed food best or supplements?
There is a lot of misconception when it comes to pet food. Grains are not bad for pets as long as they are the right kind, high-quality and easy to digest. They provide many essential amino acids that are not found in animal products. Royal Canin and Science Diet are both high quality brands with lots of research, data and good quality control. Switching to the recommended diet is the best thing you can do for Mercy. The diet contains controlled protein, controlled phosphorus, controlled potassium and additional omega three fatty acid supplements as well as antioxidants. You can certainly supplement her as it is not likely to hurt but the main control for kidney disease will be found with the protein and phosphorus. I hope this helps and please feel free to post any additional questions.
