A cat’s overall well-being can quickly become compromised when their urinary system is not at optimum health. Because your cat’s diet impacts what they eliminate, nutrition can play a critical role.

In looking over Weruva's website, I see that they claim their food to be very low in phosphorous level. That's good, as phosphorous levels in the food should be low in cats with kidney problems. The problem that I see with the food is that is does not state if it is high in protein or not. The website says it has high quality protein, but does not provide if there is a restricted protein or not in the food. In cats with high renal numbers, it is recommended to have restricted protein levels in the food. That's because many of the toxic products that accumulated in the blood due to kidney problems are due to protein breakdown, so it's important to have reduced levels of protein in the diet. Because cats are obligate carnivores, however, this protein restriction has to be done with care. Given I cannot find any information about this food being low in protein, I would not recommend feeding it to Twitchy. It would be better to feed her a kidney formulated diet, such as Hill k/d or Royal Canin renal. I would feed her a wet food instead of a dry kibble.

Thanks for using Petco Pet Education Center, formerly Petcoach. I am so sorry to hear about Anano. Although the royal Canin renal diet is ideal, it’s more important that he eats SOMETHING. So go ahead and feed him the meat. Then contact your vet to see if he or she has any other testing or treatments to try. Best wishes to you and Anano.

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!

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.

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.
