Question:

Wet Food Recommendations for Cat w/ Hyperthyroidism & Early Kidney Disease?

I'm really hoping for some guidance here. My lovely cat, Max, was recently diagnosed with hyperthyroidism and early-stage kidney disease. I'm devastated and feeling pretty overwhelmed by all the diet changes we're facing. The vet recommended switching him to a wet food diet to help with both conditions, but I’m having trouble figuring out which brands are actually good. There are so many options, and I just want to make sure I'm giving him the best possible care. I’ve heard that lower protein and phosphorus levels are key, but I’m just not sure which products fit the bill. If anyone has been through something similar with their cat and has recommendations for specific brands or formulas—especially those that won’t break the bank—I’d really appreciate your help. Thanks so much!

Answer:

Hello! It's great that you're considering your cat's dietary needs so carefully given their hyperthyroidism and early kidney disease. Managing these two conditions can indeed be a bit tricky, but with the right approach, you can help your furry friend feel their best.



For cats with hyperthyroidism, diets lower in iodine can be beneficial, as iodine is a key element in thyroid hormone production. On the other hand, with kidney disease, you want to focus on diets that support kidney function by being lower in phosphorus and sodium while having higher-quality proteins. Moisture is also important, so wet food is a good choice as it helps keep your cat hydrated.



At home, you can try serving smaller, more frequent meals to manage energy levels and reduce the strain on your cat's kidneys. Always make sure fresh water is available.



Watch for any signs indicating a worsening of their condition, such as increased vomiting, diarrhea, significant weight loss, or changes in behavior. These could mean that your kitty's conditions are progressing or that they aren't getting the nutrients they need.



Remember, each cat is unique, especially with concurrent conditions like these. I highly recommend booking a video consult with one of our veterinarians on Dial A Vet to personalize your cat's diet plan and ensure they're on the best path to health.

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
