The Best Hypoallergenic Food For Your Cat

Like any animal or human, cats are known to have allergies- although some more than others. To combat this problem, pet food brands have begun making hypoallergenic cat food, and while this definitely a great idea, it does bring up one question: which of these brands makes the best hypoallergenic cat food?


Before figuring out the best hypoallergenic cat food to buy, perhaps it is important to first define what that means. Essentially, hypoallergenic foods are anything made with limited or alternative ingredients. For example, a cat food that is grain-free would be considered hypoallergenic just as a cat food that does not use chicken or soy products would be as well.

If a cat has a reaction to quite a few ingredients, it's especially crucial to pay attention to what products and additives may be substituted in when another is taken out. In general, hypoallergenic cat foods can vary in what they include and what they do not, and because of this system, pet owners are often able to find the pet food that will suit their feline's needs.


A pet owner who has never been around a cat who has allergies may be unsure as to what to symptoms may be pointing directly to their feline having an allergic reaction. Some of the biggest indicators would include hair loss, sneezing, itchy and irritated skin, vomiting, diarrhea, and swollen paws.

If these behaviors are noticed, the next step would be to schedule an appointment at the vet and have your cat examined. Not only will this confirm the diagnosis of an allergic reaction, a vet can help isolate what specific ingredient(s) may be causing it and help determine if a hypoallergenic cat food will help.

Best Hypoallergenic Food For Your Cat


As mentioned before, hypoallergenic cat foods can vary in what they contain, but in order to find the one best suited for your needs, it's vital to pay attention to exactly what ingredients are listed and how these substances may interact with your cat. A big turn-off in searching for the most suitable kind of food would be a brand that promises no meat or very limited meat products.

Studies have shown that cats are carnivores, and their digestive systems work best when breaking down high levels of protein. In fact, without enough protein, the organs and muscles of a cat would start to break down instead (Feline-Nutrition). In this case, hypoallergenic cat foods that do make promises of using plant-based substances as an alternative to meat-based products should be regarded carefully as these brands could have negative effects on your feline.


Once finding a hypoallergenic diet for your cat, another important factor to consider is how to make this switch. Rapidly changing an animal's diet within one day could upset a cat's digestive tract and cause negative side effects like vomiting and diarrhea. It is recommended that at least a week or more--depending on how finicky the cat is--should be designated to gradually switching the feline's diet (PetMD).

The most effective way to do this would be to start by mixing a little of the new food in with the old diet, and day by day, continually add more of the new food until that is purely what the cat is consuming.

One of the things that is most underestimated by cat owners is the resistance they will face from their pets. Cats can be very picky eaters, and they do not always transition to a new diet smoothly. Although a week is what is typically recommended for making this switch, it's not uncommon for it to take longer.

The most critical thing to remember about this transition process is not to try and starve your feline into eating their new food, and if you do notice they have stopped eating, then you need to cut back on the amount of the new diet that you are adding to the old one.

In the worst case, the cat could even develop hepatic lipidosis, which results from a period of starvation longer than twenty-four hours--and if this not treated, this disease can lead to death.

While some people may find the right hypoallergenic cat food on the first try, this is not always the case. Cats, like humans, have their own unique body chemistry and what may work perfectly for one feline may yield limited results for another. Even if a cat has been successfully introduced to a new brand of pet food, you will not see their symptoms resolve immediately. Typically, you should wait a few weeks to see if there's a difference before switching to another brand.

Although there are drawbacks and benefits with each product, the one that seems to be the best hypoallergenic cat food out of these options is the ROYAL CANIN brand and there's a couple of reasons for this. Firstly, ROYAL CANIN introduced different ingredients in their food that specifically targeted a bunch of issues instead of just solving one--such as digestion or immune system health.

It was mentioned that one of the main symptoms that indicate an allergic reaction is irritated and itchy skin. ROYAL CANIN specifically puts emphasize on including ingredients that help heal these damaged areas as many cats don't even switch over to hypoallergenic food until they've already had an allergic reaction.

The biggest issue found with ROYAL CANIN was the price, and while this might be exhausting in the long run, it could be less worrisome than your cat vomiting excessively or possibly receiving a bad batch of the product. Overall, while each brand has features that make it unique and worth considering, ROYAL CANIN's emphasis on helping cats recover from previous allergic reactions and dealing with various health issues make it outshine the rest.
