There is no cure for feline kidney disease, but there are many home treatments that can reduce symptoms and increase the life of your cat.
Diet Change
There is some controversy surrounding diets for cats suffering from kidney disease. Conventional treatment dictates reducing the fat and protein content of your cat's food, but some studies are dismissing this idea. Since cats get all of their nutrients from protein, removing them from this source seems counterintuitive.
All experts do agree on one thing: Feed your cat whatever he will eat! One of the main symptoms of feline kidney disease is weight loss and decreased appetite. Thus, if your cat will only eat high protein food, feed him that. It's important that he eats.
Try to feed high quality food that doesn't contain cheap fillers such as corn, wheat, preservatives and meat byproducts. Avoid dry food, which is high in carbohydrates and other things that your cat doesn't need, and will have a harder time breaking down.
It's also important that he drinks, so keep all water fresh and make it more enticing with meat broth, tuna juice or clam juice if necessary. Though high in fat and protein, wet food can help supplement your cat's fluid intake.
Supplements
If you can't get your cat to eat much, supplement his food with vitamins that will help his body function, such as omega-3 fatty acids and vitamin B complex. Antioxidants such as vitamins C and E help cleanse the body. Vitamin A is important to the kidneys as well. Most cat foods contain sufficient levels of taurine. If your cat isn't eating much, taurine is an enzyme crucial to his internal functions, so supplement with that as well.
If you can't get your cat to eat the vitamins, force feed as you would a pill, to ensure he is getting the nutrients he requires.
Herbal Treatment
Herbs such as burdock and dandelion have been shown to slow the progress of kidney disease. Other herbs can be used to relieve the symptoms, such as slippery oak, which reduces vomiting and nausea. Alfalfa and marshmallow mixtures can also be given daily to reduce symptoms.
The homeopathic mix Nux vomica reduces the symptoms of toxicity such as nausea and vomiting. Natrium muriaticum helps the body more effeciently use water, which will reduce excessive thirst.
Additional Treatment Options
Acupuncture has been known to help feline kidney disease, because it stimulates the kidneys and boosts overall vitality of your cat. Daily grooming does the same thing. Simply brushing your cat once a day helps stimulate the kidneys by stimulating the glands that produce healthy oil in the skin.
Provide your cat with mild, daily exercise, preferably outside where he can receive fresh air and sunlight.
Cats can live a long time with kidney disease, so do what you can to make your cat more comfortable. Just a few small diet changes and extra supplements can reduce progression of the disease and help your cat live a healthier, happier life.
