Quick answer: Combine drained no-salt-added tuna, plain pumpkin purée, egg, and enough oat flour to form a soft dough. Bake tiny pieces until set and keep the finished treats refrigerated.
Pumpkin makes a useful moisture ingredient, but the label must say plain pumpkin—not pumpkin pie filling. The tuna remains the main aroma, while the pumpkin keeps the dough from becoming as dry as many fish biscuits.
This is not a digestive treatment and it should not be used to manage constipation or diarrhea without veterinary guidance. The recipe simply offers a controlled way to use a small amount of plain pumpkin in an occasional treat.
Why this version is practical
- Pumpkin adds moisture without dairy or oil.
- Tuna keeps the aroma strong at a small serving size.
- Resting the dough prevents unnecessary flour from being added.
- The softer center can be broken into tiny training pieces.
Ingredient decisions that matter
Pumpkin label: The ingredient list should be pumpkin only. Pie filling can contain sugar and spices, including nutmeg.
Moisture varies: Some pumpkin purées are watery. Let the flour hydrate before altering the ratio.
Tuna remains occasional: Pumpkin does not transform a tuna treat into a complete food or medical product.
Tuna and Plain Pumpkin Cat Treats
Small tuna treats with plain pumpkin purée, egg, and oat flour for a soft-centered baked texture.
- Prep
- 12 minutes
- Cook
- 15–18 minutes
- Total
- 45 minutes including cooling
- Yield
- About 28 small treats
- Storage
- Refrigerate 3 days
Equipment
- Mixing bowl
- Fork or food processor
- Parchment-lined baking sheet
- Measuring cups and spoons
- Food thermometer when starting with raw animal protein
Ingredients
- 1 can (5 oz / 142 g) no-salt-added tuna in water (drained)
- 1/4 cup (60 g) 100% plain pumpkin purée (not pie filling)
- 1 large egg
- 1/2 cup (about 50 g) plain oat flour
Instructions
- Preheat: Heat the oven to 325°F and line a sheet pan with parchment.
- Blend the moist ingredients: Mash tuna, pumpkin, and egg until the fish is finely distributed and no large clumps remain.
- Add the binder: Fold in oat flour. Rest the mixture for five minutes so the flour hydrates before deciding whether it needs another spoonful.
- Shape: Spread to 1/4 inch thick and cut very small squares, or pipe small dots with space between them.
- Bake and cool: Bake 15 to 18 minutes until set. Cool completely; the center may remain slightly softer than the three-ingredient tuna version.
What “done” should look and feel like
The surface should be dry, the base should release easily, and the center should feel set rather than wet. Because pumpkin retains moisture, these treats will not become cracker-dry unless overbaked.
Pipe uniformly sized dots for the most predictable bake. Uneven pieces create a tray with dry small treats and underdone large ones.
How much to serve
Offer one small cooled piece. A cat unfamiliar with pumpkin should receive only a crumb first. Stop if it causes vomiting, diarrhea, or appetite changes.
Because ingredient brands and treat sizes vary, calculate calories from the labels you actually use. Divide the batch total by the number of finished pieces, then fit that amount inside your cat’s daily treat allowance rather than guessing.
Storage and food-safety plan
Refrigerate for up to 3 days. Freeze extras for one month and thaw in the refrigerator. Do not store moist pumpkin treats in a countertop jar.
Discard any portion that develops an unusual smell, visible moisture, mold, or texture change. When in doubt, throw it away; home-baked treats do not contain the preservatives used in many commercial products.
Useful substitutions—and what not to substitute
- Use plain cooked salmon only with a salmon-specific ratio.
- If pumpkin is watery, blot it briefly rather than doubling the flour.
- Do not substitute sweet potato pie filling, baby food containing onion, or sweetened squash purée.
Common problems and fixes
The dough spreads
The pumpkin or tuna retained too much liquid. Rest five minutes, then add oat flour one tablespoon at a time.
The treats are gummy
Make smaller pieces, extend the bake slightly, and cool completely before judging the texture.
The cat refuses pumpkin
Do not disguise it or withhold regular food. Use a plain tuna treat instead.
When this recipe is not the right choice
Avoid the recipe for cats with fish or egg allergy, a prescribed gastrointestinal or urinary diet, diabetes, or any condition for which the veterinarian has limited treats. Pumpkin is not automatically appropriate for every digestive problem.
Frequently asked questions
Is canned pumpkin safe for cats?
Plain 100% pumpkin can be used in a small treat amount, but pie filling and seasoned products should be avoided.
Will these treats treat constipation?
No medical claim should be made. Constipation can require veterinary assessment, especially when persistent or accompanied by straining.
Can I make them flour-free?
Use a separately developed flour-free recipe; removing the binder changes the structure and yield.
How long do they last?
About three days refrigerated, or up to one month frozen.
Can they replace wet food?
No. They are occasional treats only.
