How to make Frozen Tuna Broth Cat Treats

Frozen Tuna Broth Cat Treats takes about 4 hours 2 minutes from start to finish and makes 16 cubes. It is an easy recipe. You will need a mini ice cube tray. Read through every step once before you start, and set out all the ingredients so nothing is missed.

Ingredients and why they are here

You need 2 ingredients. Each one is checked against the ingredient safety guide for cats.

  • 1 can tuna in water (5 oz), not drained: Packed in water, occasionally only.
  • 1 cup onion-free chicken broth or water: Homemade or onion- and garlic-free low-sodium broth only.

Step-by-step instructions

  1. Blend the tuna with its water and the broth until smooth.
  2. Pour into a mini ice cube tray.
  3. Freeze until solid. Allow about 4 hours.
  4. Serve one cube on a saucer.

Tips for success

  • Use a mini or silicone tray for cat-size cubes.
  • Serve on a plate, not the floor, so melting is easy to clean.
  • Swap tuna for chicken for cats on a low-fish diet.

How to store it

Let everything cool completely before you pack it away, since trapped steam causes sogginess and mold. Keep it in the freezer for up to 2 months. If anything smells off or shows mold, throw it out.

How much to serve

One cube a day. Each cube has about 5 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.

Why cats love it

Keeps cats cool in summer. Adds water to their diet. Two minutes of prep.

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. Chicken Broth: Homemade or onion- and garlic-free low-sodium broth only. 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.
