Home Cats DIY Cat Treat Recipe with Sardines

DIY Cat Treat Recipe with Sardines

Sardines are a high protein food that can be very beneficial to cats. These little fish are also packed with important nutrients including Vitamin B-12, Vitamin D and Omega-3 Fatty Acids. This DIY cat treat recipe can be fed to any cat, as long as they don't have allergies or food sensitivities.

Sardines should be fed sparingly, as fish can contain heavy metals and canned fish has a high salt content. I wouldn't include sardines in my cats' daily diet, but they're great to include in a homemade cat treat recipe.

I enjoy making DIY cat treat recipe options because I can control exactly which ingredients are used and how the treats are prepared. When possible, I look for organic, all-natural, whole food ingredients. I try to include superfoods that add a nutritional boost to pet's diet.

  • Method: Baked
  • Cuisine: Baked Treats


  • 1/2 cup whole wheat flour
  • 1 egg
  • 3.75 ounce can of sardines packed in water or oil


Preheat oven to 350˚F.

In a small mixing bowl combine the flour and egg. You can puree the sardines before adding them to the mixture, but you don't need to. As you can see in my video guide above, you can simply mash them as you mix the ingredients and they'll break into pieces small enough for the treats.

Mix all of the ingredients together until it forms a dough. If the dough is too sticky, you can add small amounts of flour until it's a consistency similar to cookie dough.

Take about one teaspoon of the dough and roll it into a ball. Flatten the balls on an un-greased cookie sheet. Bake this DIY cat treat recipe for approximately 10-12 minutes. You'll know the cookies are done when they begin to brown and crack on the top.

Once the cookies have cooled completely, you can serve them to your pet. Keep in mind that these treats will add additional calories to your cat's diet, so you'll want to feed them sparingly to avoid unnecessary weight gain.
