Ingredients
- 1/2 cup canned tuna in water (drained)
- 1/4 cup cooked sweet potato (mashed)
- 1 tablespoon olive oil

Why These Ingredients?
Tuna
Tuna is not only delicious but also light and easy on your cat’s stomach. It’s packed with protein and omega-3 fatty acids, both of which are essential for maintaining a healthy coat and immune system.
Tuna is also naturally low in fat, making it a perfect choice for cats with sensitive digestive systems. And let’s be honest, your cat will probably eat the tuna straight out of the can, even without the other ingredients.
Sweet Potato
Sweet potato is a gentle, fiber-rich vegetable that helps regulate digestion. It’s perfect for cats with sensitive stomachs because it’s easy to digest and provides just the right amount of fiber to keep their system regular.
Plus, sweet potatoes are packed with vitamins A and C, which help keep your cat’s immune system strong and their coat shiny.
Olive Oil
A bit of olive oil helps bind the ingredients together and adds healthy fatty acids that support skin health and energy. It also helps with hydration, which is important for cats who don’t drink enough water.
Olive oil is gentle on your cat’s digestive system and works as a nice flavor enhancer. Just a tablespoon goes a long way!
Step-by-Step Instructions

This recipe couldn’t be simpler—just follow these steps and you’ll have a soothing, delicious meal for your cat in no time!
Step 1: Drain the Tuna
Open the can of tuna and drain the excess water. You don’t want the liquid in your mix—just the solid tuna. Once drained, use a fork to break the tuna into smaller pieces. If your cat is particularly picky, you can even mash it a little for a smoother texture.
Step 2: Cook and Mash the Sweet Potato
While the tuna is draining, cook the sweet potato. Peel and chop it into small chunks, then steam or boil until soft. Once cooked, mash the sweet potato into a smooth puree. Make sure there are no lumps or chunks that could be difficult for your cat to digest.
Step 3: Mix Everything Together
In a bowl, combine the tuna, mashed sweet potato, and olive oil. Stir everything together until well mixed. The olive oil will help smooth out the texture and make the mix more moist and flavorful.
Step 4: Serve and Cool
Allow the mixture to cool to room temperature before serving. Cats are picky about hot food, and you don’t want to burn their little mouths. Once cooled, serve it in their bowl and watch them enjoy.

Portioning & Storing
Portioning
For an average-sized cat (around 5–8 pounds), 1/4 to 1/2 cup should be enough for one meal. You can adjust the portion based on your cat’s size, but remember, this is a supplement to their regular meals, not a full meal replacement. Serve this 2–3 times a week for the best results.
Storing
Leftovers can be stored in an airtight container in the fridge for up to 3 days. You can also freeze the portions for up to 1 month—just thaw them out in the fridge and warm them up before serving.
Common Mistakes
- Not draining the tuna properly – Be sure to drain the tuna fully before mixing it. Excess water can make the texture off and dilute the flavor.
- Using sweet potato with skin – Make sure to peel the sweet potato before cooking it. The skin can be hard to digest for cats.
- Using too much olive oil – While olive oil is great for your cat, too much fat can upset their stomach. Stick to 1 tablespoon.
- Feeding this as a full meal – This should be served as a supplement, not a replacement for your cat’s balanced diet.
