Quick answer: A treat ball DIY project turns part of your cat's daily food into a hunt. Cut a few holes in a clean plastic bottle, hollow cat ball or sealed cardboard tube, add a measured portion of dry food, and let the cat roll it. Start with large holes so food drops easily, then make holes smaller as your cat improves.
Indoor cats often eat from a full bowl in seconds and then have nothing to do. A treat ball changes that by making the cat work for each piece of kibble: batting, rolling and chasing until food falls out. It is one of the simplest forms of puzzle feeder, and it can be made from items most homes already have.
This guide gives three builds of rising difficulty, a ladder for making them harder over time, and the safety rules that keep homemade feeders from becoming a hazard. For the wider range of options, see our DIY cat toys and puzzle feeders hub.
Why Indoor Cats Benefit From Food Play
International Cat Care describes puzzle feeders as tools that help meals last longer, increase physical activity and provide a brain teaser, while letting cats express their natural hunting behaviour. For a cat that never goes outside, those few minutes of effort at each meal can be a meaningful part of the day.
Food play can also help with weight. VCA Animal Hospitals defines obesity as an accumulation of excess body fat that leads to excess body weight, and slower eating plus more movement are part of how many owners approach it. A treat ball is not a weight-loss plan on its own, but it is an easy way to add activity without extra food.

Treat Ball DIY Build 1: The Bottle Roller
This is the easiest build and a good introduction for cats new to puzzle feeders.
- Take a small, clean plastic drinks bottle, about 500 ml, and remove the label and the ring under the cap.
- Rinse and dry it thoroughly.
- Cut three or four holes along the side, each slightly larger than a piece of your cat's kibble.
- Smooth the cut edges with fine sandpaper or a nail file.
- Add a small portion of dry food and screw the cap back on.
- Lay it on its side on a rug and roll it once to show your cat what happens.
Bottles are noisy on hard floors, which some cats love and others find frightening. Start on a rug or carpet. If the cat is nervous, take the cap off so food falls out faster at first.
Build 2: The Hollow Ball Upgrade
Plastic hollow cat balls, the kind with holes all round, can be turned into a treat ball with very little work.
- Choose a ball large enough that your cat cannot get its mouth round it.
- Check the existing holes are larger than a piece of kibble; widen one or two with a craft knife if needed.
- Push a few pieces of dry food through the holes.
- Roll it gently across the floor to start play.
Because these balls roll more freely than a bottle, food comes out at random, which many cats find more exciting. They are also easier to wash. Replace the ball if it cracks.
Build 3: The Sealed Tube Spinner
A cardboard tube from kitchen roll can make a quick, disposable treat ball.
- Fold one end of the tube inwards and press it flat to close it.
- Cut two or three small holes along the side.
- Drop in a few pieces of kibble.
- Fold the other end closed.
- Roll it across the floor for your cat to bat.
These tubes wear out quickly and should be thrown away once they get soggy or chewed. They work well as a first try before you invest time in a sturdier build. Our guide to a toilet paper roll puzzle feeder has more tube-based designs.
A Difficulty Ladder for Treat Balls
International Cat Care advises starting with easy feeders and increasing the difficulty gradually, for example by making the holes smaller as the cat learns. A cat that fails at first may lose interest entirely, so begin simply.
| Level | Change | Signs the cat is ready to move up |
|---|---|---|
| 1 | Large holes, cap off, a few pieces | Cat rolls the feeder and eats readily |
| 2 | Cap on, holes still large | Cat empties it in under a few minutes |
| 3 | Smaller holes | Cat stays engaged and empties it eventually |
| 4 | Mix two builds in one session | Cat moves between them with confidence |
| 5 | Hide a feeder for the cat to find | Cat searches without prompting |
If your cat stops playing, step back a level. The goal is engaged effort, not frustration. Our DIY vs store puzzle feeder challenge levels guide compares how homemade and bought feeders fit into the same ladder.
Portioning and Safety Rules
Food in a treat ball should come out of the daily allowance, not be added on top. Measure your cat's usual daily dry food in the morning, then take each treat ball portion from that amount.
- Use dry food or small, hard treats only; wet food will clog and spoil.
- Wash plastic feeders after each use and let them dry fully.
- Throw away cardboard feeders once they are damp, torn or chewed.
- Never add string, ribbon or elastic to a homemade feeder.
- Supervise the first sessions with any new build.
- Remove the feeder if pieces start to break off.
The no-string rule matters because many cats swallow linear items during play. Our egg carton puzzle supervision and string rules guide explains the risks in more detail.

Choosing the Right Floor and Room
Where the ball rolls changes how hard the game is. On a smooth wooden or tiled floor, a bottle roller travels a long way with each tap and food scatters widely, which suits confident, energetic cats. On a rug or short carpet it moves slowly and stays close, which is easier for beginners, nervous cats and older cats who do not want to chase far.
Pick a room with no gaps under furniture where the ball can get stuck, or block those gaps with a rolled towel. A ball lodged under the sofa with food still inside teaches the cat that the game ends in disappointment. Hallways work well because they give a long, clear run with walls on both sides.
Keep the play area away from the litter tray and water bowl, since cats generally prefer to keep eating, drinking and toileting areas separate. If you share the home with a dog, run treat ball sessions behind a closed door so the cat can play without competition.
Keeping Interest Over Weeks
A cat that sees the same ball every day may lose interest. Ohio State's Indoor Pet Initiative recommends keeping a batch of toys that can be rotated a few at a time to keep them interested, and the same approach works for feeders. Keep two or three builds and swap them every few days.
Use treat balls at different times of day and in different rooms. A morning session before you leave for work and an evening session in a quiet room can both help. For senior cats, our gentle toilet paper roll feeder for senior cats offers an easier option.

Treat Ball DIY FAQ
How do I make a DIY treat ball for my cat?
Clean a small plastic bottle or hollow cat ball, cut a few holes slightly larger than your cat's kibble and smooth the edges. Add a small portion of dry food, close it and roll it across a rug to show your cat. Start with large holes so food falls out easily.
Are homemade treat balls safe for cats?
They are safe when made from clean, sturdy materials with smooth edges and no string, ribbon or small parts. Supervise the first sessions, wash plastic feeders after use, throw cardboard ones away when damp or chewed, and remove any feeder that starts to crack or break.
How much food should go in a treat ball?
Take it from your cat's normal daily allowance rather than adding extra. Measure the day's dry food in the morning, then use a small portion for each treat ball session. Start with just a few pieces so the cat succeeds quickly, and increase the amount once it understands the game.
What if my cat ignores the treat ball?
Make it easier. Use bigger holes, leave the cap off, add a few highly liked treats and roll it yourself to show the cat food coming out. Try a quiet room on a soft surface. If the cat still ignores it, try a different build such as a cardboard tube or hollow ball.
