Ensure it holds together but isn't packed too tightly for easy tipping in the next step. Credit: The Spruce / Adrienne Legault Tip the Cake Onto a Plate Take the measuring cup, now full of the cake ingredients, and carefully tip it onto a plate. The easiest way to do this is to hold the measuring cup upright, and hold the plate face-down on top of the measuring cup. Carefully flip them over so the plate is now face-up, and you can lift the measuring cup off the plate. Don't worry if it doesn't come out perfectly—just shape the cake as needed.

Take your piping bag or plastic bag and fill it with the mashed potatoes. Make sure the mashed potatoes are plain and unseasoned.

Cover the top of the cake with the piped mashed potatoes. Again, it doesn't have to be perfect; just smooth the top of the potatoes with a knife, or get creative and make a pattern or design in the mashed potatoes.

Consider adding a tiny cake topper or a birthday candle or two to the top of the cake so it looks really festive. Don't forget to get some pictures of your cat with their birthday cake. Just make sure to remove any inedible items that they might choke on before they dig in.

For example, you can use canned salmon instead of albacore tuna, and you can use unseasoned, cooked turkey, duck, or beef instead of chicken. Instead of topping the cake with catnip, you can decorate it with your pet’s favorite treats. Chopping up the treats and sprinkling them on top can also make a fun design and make the cake irresistible to your cat. This recipe keeps things simple and doesn’t require baking, as all of the ingredients are already cooked. Unlike other recipes that use ingredients like raw meat, eggs, and flour, no baking is necessary. Explore more: Cats Getting Started
