About Low Protein Diets For Cats

As this type of cat food is meant specifically for kitties with some health problems, it would be wise to learn everything that you can about what to look for, why you might need it, and other general information about non prescription low protein cat food.

How to Choose the Best Low Protein Cat Foods

As with anything, shopping for cat food is a process. You want the best for your cat, so you’re not going to take the decision lightly. As humans, we can sometimes take food for granted because we have so many options and are often not very limited.

For cats with health conditions, this couldn’t be further from the case. Not only will they be eating this food every day, but their health will depend on the contents of the food that they eat. The first thing that you’re going to want to do is to listen to your vet.

Your vet is probably the one who told you that your cat needs a low protein cat food, so listen to what they say so that you know what to look for in terms of ingredients and nutrients in your cat food.

Finding Low Protein Cat Foods

Knowing what you need is one thing—finding it is another. Luckily, we’ve compiled a complete guide to make that a little bit easier. In our guide, we’ll show you what is unique about each of the low protein cat foods that we reviewed and what they each bring to the table.

Using a combination of the requirements provided by your vet and our extensive research of the best low protein cat foods on the market, you should be able to pinpoint the cat food that meets the perfect combination of health, nutrition, taste, and affordability.

One thing that you should be prepared for is that you might not get it right the first time. It’s important to not be hard on yourself because this could be a process of trial and error. Finding the right food isn’t always an exact science so it’s crucial to have patience.

What Are Some Important Features to Look For in Low Protein Cat Foods?

With so many options out there, many people are left wondering what specific features and ingredients should they be looking for when shopping for cat food. Sometimes, the answer is going to vary based on how particular you need to be with your cat’s diet. However, there are some general guidelines that we suggest you follow and ingredients we recommend you look out for.

The most important thing to include in these foods is a low-protein composition. After that, there are some other ingredients to keep an eye out for. One of the things that are good to look for is restricted phosphorous. You also want to include Omega-3 fatty acids from fish whenever possible. These ingredients are going to help support the kidney function of your cat.

It’s also a good idea to pay special attention to foods that offer some form of immune system support. This can be delivered in the form of a multivitamin and antioxidant complex, which work in conjunction to strengthen your cat’s immune system.

Moisture Content

Finally, you want to try and provide your cat with the most natural food possible by including a high moisture content in their diet whenever possible. In nature, the prey of cats provide a lot of moisture content and attempting to replicate that can help with their kidney function. It also helps a couple of other things like the prevention of urinary tract function and the promotion of healthy weight loss.

If you do decide to try and include some more moisture in the diet of your cat, you’re going to want to check out some of our recommended low protein cat foods!

Additional Tips & Tricks for Selecting Low Protein Cat Food

While you already know what ingredients you should be looking for when shopping for the best low protein cat food for your furry friend, there are some other tips and tricks that we feel you should be aware of that will help you navigate the world of cat foods.

When you are looking at the back of your cat food, there are some things that you need to know. There should be a section that is labeled “Guaranteed Analysis” on the back of the cat food bag.

In addition to the percentage of protein content, you also need to check out the overall ratio, moisture ratio, ingredients, and protein sources. Not all protein sources are created equal, so make sure that the protein source is suitable.

Feeding a cat a diet with low protein seems counterintuitive since protein is essential to their survival, but it can absolutely be done with the right amount of research and preparation. With the right low protein cat food, your cat can be healthy and happy for the years to come.
