How to store it
Let everything cool completely before you pack it away, since trapped steam causes sogginess and mold. Keep it in the fridge for up to 2 days. If anything smells off or shows mold, throw it out.
How much to serve
Half a cake per cat as a special-day treat. Each half cake has about 90 calories. Treats and toppers should stay under 10 percent of your cat’s daily calories, so cut back their regular food a little on days you serve extra.
Swaps and variations
No tuna in water? Use canned salmon. Change one ingredient at a time so you can tell how each swap affects the texture.

Feeding tips for cats
Cats can be cautious with new foods. Offer a tiny amount next to something familiar, and be patient if your cat sniffs and walks away the first time. Warm refrigerated food to room temperature, since cats prefer food near body temperature. Cats with kidney, thyroid or urinary conditions may need a special diet, so ask your vet before adding new foods.
Make it ahead
To save time, measure and prep the ingredients the day before and keep them covered in the fridge. Label containers with the recipe name and date so you always know what to use first. Most of the work in this recipe is hands-off, so it fits easily around a busy week.
What to watch for
Watch your cat’s litter box for a few days after any change. Call your vet if your cat vomits repeatedly, has diarrhea, or stops eating for more than a day, since cats that skip meals can develop liver problems quickly. If you think your cat ate something toxic, call your vet or an animal poison control line right away.
Safety notes
Tuna: Packed in water, occasionally only. Oat Flour: Fine as a binder in treats. Cats need very little carbohydrate. Never add onion, garlic, chocolate, grapes, raisins, xylitol or salt, and check the safety guide before trying a new ingredient with your cat. This recipe is general information, not veterinary advice.
