What's the best food for senior cats with kidney issues & is rescue remedy safe?

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.

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!

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.

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

Yes, it’s fine. The kidney care diet is appropriate for all cats, it just helps protect the kidneys and not make them work harder than necessary. Thanks for using Petco Pet Education Center, formerly Petcoach to help you get answers to your veterinary questions.

Wow, 23 is very old. You must take very good care of him. I am sorry to hear about his diagnosis. Renal disease as you probably already know is a chronic condition. Dietary change can be a major factor in extending the length and quality of cat's live who have it. However, in a 23 year old cat I would usually recommend just feeding whatever makes him happy. Nutritional intake in general is very important right now, so having to fight with him to get him to eat will end up being quite stressful and maybe counterproductive. If you are dedicated to a kidney friendly diet and the commercial stuff isn't working, you can certainly start thinking about home made diets. This is a link to a website that will guide you into making diets that are good for patients with kidney disease. I believe it is free for the first 14 days. Most of the diets they suggest do require supplementation with certain vitamins and minerals, however, and without them other problems may arise. Hope this helps and best of luck with PJ.

I would opt for a prescription kidney diet (Hill's K/D or Royal Canin renal) instead of any over the counter option if he has kidney disease especially, because the mainstay of treatment for this is the diet alone. This is also ok for his pancreatitis for now and hopefully he will get over this pancreatitis episode soon with the treatment recommendations through your vet. Pancreatitis in cats is often associated with a triaditis (3 disease) condition affecting both their intestines (IBD), pancrease (pancreatitis) and liver (cholangitis), so its imperative to follow your vets instructions on follow-up care as well. Here is more information on this condition in cats --> https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952234 I do hope that your pet Cat is going to be ok moving forward. Best of luck and take care.
