Best Cat Food for Kidney Disease Buying Guide & FAQ
What Are the Signs of Kidney Disease in Cats?
One of the most obvious signs of kidney disease is frequent urination. This happens when the kidney is not able to hold liquids properly, and so they tend to pee a lot. When you notice your cat taking more potty breaks than usual, they are likely to be suffering from kidney disease. Another sign that your cat is suffering is when they drink water a lot. This can be attributed to the fact that because they are peeing a lot, their body needs more fluids to make up for it. You can also tell your cat might be having kidney issues when their breath smells like ammonia. They might even lose weight and have a decrease in appetite. Their urine can be bloody or cloudy, and they may experience some vomiting and diarrhea. You may also notice that their tongue becomes a brownish color and they may develop mouth ulcers, especially on the gums.
What to Look For in a Cat Food for Kidney Disease
- Ingredients: Generally speaking, natural ingredients are the best because they have a lesser chance of triggering allergies. Components like artificial preservatives, colors and flavors should not be in cat food for kidney disease. Also, to be safe, make sure the ingredients are clinically tested, or veterinarian approved, and the sources are reliable before feeding the food to the cat. With these safety measures in place, your cat's problem is less likely to deteriorate.
- Nutrients: When it comes to cat food for kidney disease, nutrients like protein and phosphorus should have a low percentage. This is because these nutrients have a direct effect on the kidney and can put extra pressure on the organ. In short, the lower the levels of these nutrients, the better it is to consume. Other nutrients, however like carbohydrates, antioxidants and anti-inflammatory sources should be in the required amount.
- Moisture: Generally, wet foods are better for the kidney than dry food because of the following reasons. Firstly, it is easy to ingest and digest and also it helps to keep the cat hydrated.
Therapeutic Kidney Diet Basics
A kidney diet should contain as low protein and phosphorous as possible, and in their place, there should be more potassium, omega-3 acids, and water-soluble vitamins. It should also include a lot of moisture so that the cat stays hydrated.
How Nutritional Requirements Differ for Cats with Kidney Disease
The significant difference between a regular cat diet and one for cats with kidney disease is the protein level. A cat's regular diet should consist mainly of protein, but they no longer can afford this luxury when they have issues with their kidney. Also, phosphorous and sodium are in minimal quantities so that it isn’t much pressure on the organ. A diet for kidneys should also be high in omega-3 fatty acids which have nutritious benefits fr the kidney. These components aid in metabolism and reduce the work the organ will have to do.
The Importance of Water for Cats with Kidney Disease
Aside from the general benefits of drinking water, it is more critical when there are kidney issues involved. Water helps to keep the cat hydrated so that their organs function as they should. In addition, it helps to dissolve minerals and nutrients so that they can quickly get to every part of the body. This means that there will be less work for the kidneys to do and so they do not deteriorate rapidly. If there is little to no water intake, then the organ is prone to failure. Kidney failure also means that waste and toxins will build up in the body and cause more problems for the cat.
