Treat your felines to this cat birthday cake made with pate, catnip, and a mashed potato "frosting!" It's easy to make and customizable, so even your pickiest kitties will love it!
Use a blender, spice grinder, or food processor to blend the cat treats into a fine powder.
Add the pate (without the liquid, if there is any) and powdered cat treats to a bowl and mix until combined.
Scoop the mixture onto a sheet of plastic wrap and wrap tightly, so the cat food mixture forms a puck or a ball, depending on how you want to shape your cake. You can chill it like this, or you can carefully press the mixture (still wrapped in plastic) into a bowl, ramekin, or mold, to make it a specific shape. I used a 4-ounce ramekin for mine.
Let it chill in the fridge for 30-40 minutes to make sure it maintains its shape.
Once chilled, remove the cake from the plastic wrap and place it on your chosen serving plate.
Use an offset spatula to “frost” the cake with the instant mashed potatoes. You may also use a piping bag and piping tips to pipe decorative borders. If your potatoes are too soft or too thick, you can adjust the consistency by adding either another teaspoon of instant potatoes or another teaspoon of water until it spreads and pipes just right for you.
Sprinkle a pinch or two of catnip on to act as sprinkles and decorate with cat treats.
