What's the best homemade diet for my cat with hyperthyroidism and kidney disease?

Unfortunately the only food that will have a chance of working on its own it’s Hill’s. The other brands have not been formulated and studied with the same purpose. It is not the gold standard treatment for Hyperthyroidism but might work in some specific cases. Hyperthyroidism is caused by a tumour of the thyroid gland, and although benign can’t be left untreated. My personal recommendation would be to discuss other treatment options which might be more appropriate given Bob’s underlying allergies and given his relatively young age. Hope this helps !

Thank you for submitting your question regarding Bitty. If his hyperthyroidism is well controlled and he has not developed any kidney disease, then he can eat a high quality over-the-counter diet. I typically recommend Purina ProPlan or Royal Canin. If he has other underlying diseases such as kidney problems, then a prescription diet would be necessary. I hope this information helps!

if she is borderline and symptomatic they can send a thyroid test that can test more than just the in house version for a more definitive complete answer. Also they do make a food tailored to hyperthyroid cats that can help maintain the thyroid level. It is not safe to do if the number it not high though and it has to be the only food she gets. It is called science diet Y/D. I would talk to your vet about sending off a complete thyroid panel prior to any changes

Most of the premium brands (Blue Buffalo, Canidae, Orijen, Royal Canin) should be fine. Stay away from store or discount brands as these typically contain low quality ingredients and more fillers. Choose a canned food that comes from the can looking like a hockey puck. It should have a named protein source of animal origin. If you must feed dry, choose a grain free diet. Stay away from foods that are minced, diced or have sauces/gravies. these are usually higher in carb content which your cat does not need.

This should not make a difference. Please check with your veterinarian if in view of the renal disease, it is advisable to change to a raw diet, as this means a lot of protein is being fed which can negatively influence your cat's kidneys, It would be ok in a healthy cat, but a cat with renal disease may not be the right candidate . lso, please do not , under any circumstances, feed beef neck parts or poultry necks, as they contain thyroid glands and your cat would be eating thyroid hormones which would make his hyperthyroidism much worse.

Unfortunately all prescription diets for kidney failure in cats are more or less priced the same, removing her from a prescription diet can potentially accelerate the disease. the alternative is home made recipes such as these ones: https://www.pets4homes.co.uk/pet-advice/2-homemade-recipes-for-cats-suffering-from-kidney-disorders.html

Hello, I am sorry I misunderstood your question earlier. I hope this response helps you. In order to stage renal failure, we need to know the urine specific gravity, blood pressure, and urine protein to creatinine ratio. Based on the values you provided, she has chronic kidney disease but I cannot stage it without further information. If the free T4 was elevated that is consistent with hyperthyroidism which often masks underlying kidney disease. Therefore, her kidney disease could be worse than we suspect based on the info you provided above. Realistically, she has two diseases and fortunately both are treatable. Ultimately, the prognosis depends on response to therapy. It is not uncommon for some patients to do well for a few years with appropriate therapy and kidney diet. Prior to treating her hyperthyroidism, her kidney disease should be treated (at home) with subcutaneous fluid therapy, antibiotics to cover for an underlying kidney infection, and vitamin B12 supplementation. After she feels better and begins eating consistently, discuss treatment for hyperthyroidism.
