Easy homemade cat treat recipe with tuna

I’ll never forget the first time I tried making homemade tuna treats for my cat, Whiskers. I thought, “How hard could it be?” Spoiler: very. I accidentally used way too much flour, and the treats came out like little hockey pucks. Whiskers took one sniff and walked away like I’d insulted her ancestors. But after a few tries (and a lot of wasted tuna), I finally got it right. Now, she comes running the second she hears the can opener. It’s our little ritual—messy, smelly, and totally worth it.

Recipe Card

Ingredients

• 1 can (5 oz) tuna in water (drained)
• 1 egg
• 1/2 cup whole wheat flour (or oat flour for grain-free)
• 1 tbsp olive oil
• 1 tbsp catnip (optional, but my cat goes nuts for it)

The tuna is the star—Whiskers would sell my soul for it. I learned the hard way to always get tuna in water, not oil. The first time, I didn’t drain it well enough, and the treats were a greasy mess. The egg binds everything, but if your cat’s sensitive, you can skip it (more on that later). The flour’s just for texture; oat flour works great if your cat’s picky about grains. And the catnip? Pure magic. Just don’t overdo it, or your cat might start levitating.

Directions

1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. In a bowl, mash the drained tuna with a fork until it’s flaky.
3. Add the egg, flour, olive oil, and catnip (if using). Mix until it forms a dough.
4. Roll the dough into small balls (pea-sized for treats, bigger for training rewards).
5. Flatten slightly with a fork and bake for 12–15 minutes until golden.
6. Let cool completely before serving. Store extras in the fridge for up to a week.

My biggest fail? Not flattening the treats enough. I made little tuna marbles, and they took forever to bake. Whiskers got impatient and started yelling at me like I was a slow waiter. Now I press them flat so they crisp up faster. Also, let them cool fully—hot tuna smells like regret, and your cat will judge you.

Whiskers goes nuts for these, but my friend’s cat, Mr. Pickles, once turned his nose up at them. Turns out, he hates catnip. Who knew? So I made a batch without it, and he devoured them. Lesson: cats have opinions. Strong ones.

These treats are great for hiding pills in (shh, don’t tell Whiskers). I crush her meds into the dough before baking, and she never suspects a thing. Way better than the wrestling match that used to happen with pill pockets.

Nutrition Info (per serving)

I was surprised how protein-packed these are—great for active cats. Whiskers is a lazy loaf, but my neighbor’s Bengal burns through them like fuel. If your cat’s on a diet, go easy—these are treats, not meals. And if they’re allergic to fish? Skip this recipe entirely. No amount of begging is worth an itchy cat.

Ingredient Swaps

I tried coconut flour once—big mistake. It soaked up all the moisture, and the treats crumbled like sand. Whiskers gave me the side-eye for days. Salmon works great, but it stinks up the kitchen worse than tuna. Banana as an egg substitute was a fluke discovery when I ran out of eggs. It adds a weird sweetness, but some cats dig it.

Tips

• Drain the tuna REALLY well. Wet dough = sad, soggy treats.
• If the dough’s too sticky, add flour slowly. Too much, and it’s cardboard city.
• Bake until lightly golden. Overcooked treats = feline betrayal.
• Freeze extras in a baggie. They thaw fast, and your cat will think you’re a wizard.
• Hide these when cooling. I’ve caught Whiskers sneaking them off the counter mid-bake.

I once left the dough unattended for two seconds. Came back to find Whiskers elbow-deep in the bowl, licking her paws like a tiny bandit. Now I mix it behind closed doors. Also, if you burn a batch (I have), just toss ’em. Charcoal-flavored treats don’t win any purrs.

FAQ

Can I use tuna in oil?
Technically yes, but your treats will be greasy, and your cat might get an upset tummy. Stick to water-packed—it’s healthier and less messy.

My cat ignored these. Help?
Some cats are snobs. Try skipping the catnip or swapping tuna for chicken. My sister’s cat only likes these if I sprinkle them with bonito flakes. Trial and error, friend.

How long do they last?
A week in the fridge, but good luck keeping them that long. I freeze half the batch because Whiskers acts like I’m starving her if she runs out.

That’s everything I know about making easy homemade cat treats with tuna! Give it a shot, and if your cat disapproves, welcome to the club. Mine still glares at me if I dare buy store-bought ones. Happy baking—may your kitchen smell like fish and your cat actually eat what you make.
