What Is Kidney Disease in Cats?
Cat owners should really know the warning signs of what kidney disease looks like in their feline friends. When their renal glands and kidneys are affected, the body will struggle to filter impurities out of the blood and to make urine the way it should.
Cats may experience more illnesses as a result of the waste buildup flowing through their bloodstream.
Diagnosing a cat with kidney disease, particularly chronic kidney disease (1), means keeping an eye out for a few key symptoms. A feline with kidney issues may have any of the following symptoms:
- Poor grooming habits compared to normal
- Weight loss
- Increased urine output and water intake
- High blood pressure
- Pale pink gums
A veterinarian can run the necessary tests to determine whether your cat is suffering from kidney disease. They will be looking at the blood for blood urea nitrogen and creatinine content. A urine sample can also reveal information that would point to an official diagnosis of kidney disease in your kitty.
Adjusting Your Cat’s Nutritional Needs
If your cat is diagnosed with kidney disease, the best thing you can do is change their diet. This gives them the best chance at normal functioning and improving their quality of life.
Another thing you can do immediately to further prevent your cat’s kidney health from deteriorating is to provide kidney health and support via Scruffy Paws Kidney Vitalize Chews.
Scientifically-backed and taste-tested by cats, these chews are a great way to keep your kitty’s kidney health on the right track.
What’s more, these tasty chicken liver-flavored chews act as a preventative measure to ensure healthy kidney function while supporting and repairing already damaged kidney function.
The main active ingredients in these chews – Astragalus & Rehmannia root – have proven to be effective in both keeping CKD at bay while alleviating symptoms in already affected cats.
After losing their own cat to kidney disease, the creator of Scruffy Paws Nutrition found that 1 in 3 cats over the age of 10 is affected by kidney issues. And, unfortunately, detecting kidney issues in cats is very much in the later stages of disease – when 60% of a cat’s kidney function is already gone.
Testimonial“I am so happy to have found your Kidney-Vitalize Chews. My 15 year old cat-Cagney was losing weight and had his blood tested. It showed he was in the beginning stages of kidney disease. My vet suggested changing his diet to a prescription kidney friendly one.. I ordered a jar of the Kidney Vitalize Chews and Cagney loved it-and actually gave him his appetite back. I just had his blood tested 4 days ago and his numbers have improved tremendously and he gained almost two pounds! “

So what do you feed them if they won't touch the wet or dry prescription food? Coby doesn't eat dry food...so I need a brand of wet foods that he will eat. I tried the raw food from Petco today and he wouldn't touched it. If I cooked chicken breast for him is that good enough? I am hoping there is a good wet food out there that someone uses that he will like so he will get the extra water he needs. HELP!!

hey Shari! Sounds like Coby can be picky, lol! Try and incorporate something he loves with the diet he needs. Chicken breast is obviously super in protein but it doesn't have all the added vitamins and minerals kitties need. We use Blue Buffalo which is natural cat food created by holistic vets and animal nutritionists - Yoda LOVES the wet food (tuna) and we use this to encourage him to eat more. I always mix the wet food with the dry (also Blue Buffalo) and I make a little dry-wet-dry layering so that Yoda has to eat enough off the top to get to the juicy part, hehe. It's always worked for us, so try it with Coby. If he loves tuna, salmon, chicken, whatever it may be... use that and mix it with his regular food. Hope this helps! Let us know. xoxo

Hi, I’ve an 11 year old whose kidney values are just creeping up tho right now urine test is negative. In being a cat mom for more than three decades I’ve gone away from dry food and my cats only eat canned. My first cat had poor food choices back in the 80’s as the pet industry was getting going. Her eating dry got her diabetic in early teens and died from complications. So any dry food for cat health issues won’t do - why on earth would these so called prescription foods have any dry food especially for kidney issues? I believe potassium is a bigger issue than protein which cats being obligate carnivores need. Vet recommended Hills k/d and I hesitate to pick up samples. My cats hate those foods except when they need weight gain (a/d), then I put them back to regular food as soon as their appetite is kickstarted again. No wonder, the ingredients in these prescription foods are horrible. We go with limited ingredients which is usually the meat they need, and grain/carb free. Most people on the cat blogs and sites are dismayed trying to find healthy food on general. So I will keep investigating and hope pet marketing stops pretending bad/wrong ingredients are okay. Thanks for letting me comment.

Hey Carol, we really appreciate your input. I, too, have noticed that even the "prescription" foods and their ingredients are not up to par with some other cat food brands (like Blue or Orijen). Even though the ingredients (especially the first 5) are not "as good" insofar that they might have gluten or corn meal, etc., these prescription foods are tested for ameliorating those types of diseases in cats but it's only due to the added formulation in it, rather than the ingredients themselves (i.e. whether protein is first vs by-product, etc.), I'm hoping one day a brand like Blue will combine their high-quality ingredients and recipes into more prescription-like foods (such as Hills) so cats can both benefit from the vet-approved formulas + ingredients free of gluten, corn, by-products, etc. We are updating our information to our readers as much as possible. We've still got lots of work to do but we hope to provide the best info out there for other cat parents! We hate to give Yoda food that's not up to our standards, so we know it must be like that too for other cat moms and dads. Thanks for commenting!!
