What Can You Put in a Cat Kong Toy?

Cats are amazing pets that have been living with humans for thousands of years. A loyal pet deserves something special to play with. Kong toys are known for their durability but how can you make them work for your cat? Here are some ideas on what you can put in a cat kong toy and how you can adapt your cat's Kong toy to make it more fun and engaging.

Dry Food

Cat kibble such as GoCat is the perfect size to stuff inside a Kong toy. Putting their food inside the food is a great way to make eating their dinner more fun. If your cat tends to rush their meals, adding their food to a Kong can help them slow down and eat more slowly. If you feed your cat wet food, you might want to skip this option unless you are happy with gravy on your carpets. 

Cat Treats

If your cat isn't interested in eating their normal food out of a Kong, there are plenty of kitty treats that you can add instead. There is a wide variety of cat treats that can be easily placed in a Kong. The best type of treat to use is a kibble treat with a creamy center. These treats appear to be a firm favorite with cats, so adding them to the Kong will make the experience more enjoyable for them.

Frozen Chicken Soup

This one sounds great in theory until you try to keep the soup in the Kong! But it is possible to plug the holes and fill the inner section with soup. However, if you put the soup in the freezer for around 20 minutes, it will be slushy and easy to work with. Once it gets to this state, it is easier to pour in and keep there. Once the soup has frozen completely in the Kong, your cat will have hours of fun licking it out. 

Scrambled Eggs

There are certain foods that cats can eat, and eggs can be one of those gray areas. Cats cannot eat raw eggs as the proteins in eggs bind with vitamins and can cause a vitamin deficiency. Cats can eat cooked eggs. Boiled and scrambled eggs are an excellent option for cats as an occasional treat. If you do make scrambled eggs, it is important not to add anything extra, such as milk or butter, as dairy can have a bad effect on your cat's stomach.


There are not a lot of fruits that a cat can eat but the ones that they can are great frozen. Bananas are fantastic frozen and can be mashed and stuck inside a Kong along with frozen blueberries. Chucks of peeled apple and melon are other great ideas. One thing that should not be fed to a cat is grapes as these are very poisonous to cats (and dogs).

Smashed Vegetables

If you are handy with a blender and have some leftover vegetables from your dinner, they are a great idea for inside a Kong. Cooked carrots, broccoli, and peas are mashed together and can be pushed inside the Kong. One thing you might want to avoid is spinach as it can cause crystals to form in the urinary tract. If you have a lot of leftover vegetables, you can freeze them in ice cube trays and pop one out for Kong when you need it. 

Chicken Pieces

Cats go crazy over fresh meat, and chicken is probably one of their favorites. It is important to remember that you are feeding them fresh chicken, it needs to be boneless. Although, there are many types of cooked meat that your cat can eat. We want to stress that this needs to be cooked meat with no bones and no fat. So cooked lean beef, cooked chicken breast, or diced liver that has been cooked are all excellent ideas to put in a Kong. If the thought of meat in the Kong doesn't appeal to you, you can pop some Meat Medley kibble into it instead. You may need to keep them restricted to around 20g of cooked meat so they don't overload themselves with calories. 


Fish comes in many forms so you have a lot of options to choose from but they aren't all suitable for cats. As a general rule, cats can technically eat any cooked fish. However, the issue is the small bones that can lodge in a cat's throat. Tinned tuna which has had the bones removed is one of the safer options for your cat, as are sardines. Yes, sardines have bones in them but they are so tiny they are not an issue for a cat to eat them. If you want to give your cat some fish without the worry of bones, Fish4Cats is perfect.

Binding Foods

Above we have listed a huge range of foods that are great for your cat, but when it comes to putting them in the Kong, they sometimes need something to hold it all together. And this is where the binding foods come in. Mashed sweet potatoes, cooked and cooled couscous, and bread crumbs are all food that can be used to bind the other foods together. These foods, especially the couscous and mashed sweet potato, are sticky and have an interesting texture. It will add another dimension to their playtime.


Catnip is a member of the mint family that is known to have a surprising effect on cats. If you have ever seen a cat "high" on catnip, you will understand why they enjoy it so much. Catnip doesn't work on kittens and is best saved for older cats. If you would rather save your Kong toy for couscous and tuna stuffing, there are plenty of Kong toys that come pre-stuffed with catnip. Or if you fancy something different from catnip, you could try some hemp treats.
