Does Your Pet Have a Protein Intolerance?

When I first started feeding my cats a homemade raw diet, I used Dr. Lisa Pierson’s chicken recipe from Once I had my grinder, the recipe was pretty easy, especially the more I made it.

This website doesn’t talk about rotating proteins so my cats ate chicken for probably three years or more. Even though I thought about giving them something different for variety, I didn’t have any other recipes and didn’t know how to make sure another protein was properly balanced.

Avoid a Protein Intolerance

As I did more research on raw feeding, I learned that feeding theTitle image - Protein Intolerance: How to Avoid It - photo of raw chicken in a bowl same protein over and over can cause allergies or at least an intolerance to that protein. So, several months ago, I started rotating their proteins.

Now, my cats eat a way better variety of meat than I do. Some of them I’d love to have for myself but they aren’t available or are too expensive. They have had rabbit, venison, turkey, duck, pork, bison and beef. I buy rabbit, duck, venison and bison from my local raw food supplier, Excel K9. I buy frozen ground turkey in bulk (5 lbs.) at the grocery store. I buy large, whole beef or pork roasts and grind them myself.

Shortly before I started rotating proteins, Christy started throwing up several times a week but I didn’t think that much of it. She’s the reason I started feeding raw since she has always had a sensitive digestive system. I didn’t give it anymore thought since she stopped when I changed her food and all seemed well.

When it was time for chicken again, I made my usual batch. Right away, Christy started throwing up again, this time pretty much every meal. I conducted a little test. I gave her canned tuna and it stayed down. I gave her pork and it stayed down. Another meal of chicken and up it came. This could all be coincidence but it seems she has probably developed an┬áintolerance. And, of course, I have 40 pounds of chicken thighs in my freezer! That’s okay, though. No more chicken for Christy. At least not for a long time.

I want to make it clear that this is not just a raw food issue. Feeding the same protein over and over in any form; canned, dry or raw, can cause allergies or an intolerance. It is important to rotate the proteins and even the brands in your pets diet.

Have you had an experience with a protein intolerance or allergy? How have you dealt with it?

  1. I know that fish protein is different from meat protein, but I didn’t know that my dog needs all kind of animal based protein. Thank you!

  2. This makes a lot of sense to me. I became a kitten owner for the first time recently. Common sense told me that a smart mammal like a cat wouldn’t want to eat the same meal every day, just as we humans generally don’t eat the same exact thing habitually. From the first weeks at home I have fed my cat a variety of proteins. No regurgitating of her meals or rejection thus far.

  3. I started rotating the protein with Truffle and Brulee a couple of years ago.

  4. Well, thankfully, my dog has no protein intolerance. At least, I don’t think she has.

  5. Interesting! We wonder if the same thing would happen with commercially prepared foods as well.

  6. TW always rotates protein and brands. I’m a fish eater who will eat chicken. She’s been buying beef and turkey. I won’t even sniff the turkey.

  7. Interesting post. It’s true that in order for an allergy to develop, the pet must first be exposed to it (sensitized) so the body’s immune system reacts. I’m not aware that repetition of exposure increases the likelihood of a food allergy. It’s my understanding that a food sensitivity actually can happen with the first exposure of the protein. Allergy and sensitivity are different conditions (I’m not real clear on how to explain it though! LOL!) but glad you discovered the issue with the chicken. It’s so frustrating to deal with these things!

  8. Rotating proteins is definitely important – my pups have had beef, chicken, turkey, duck, and lamb, and I have 3 different sources where I get them from. I think it’s awesome that you have raw-fed kitties!!
