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.
