Quick answer: Free foraging feeders can be made from a cereal box with paw-sized holes, paper cupcake cases on a baking sheet, or a cardboard takeaway tray with paper lids. Fill them with weighed dry food from the cat's vet-approved daily amount. They cost nothing, slow down eating, and keep a dieting cat busy between meals.
Helping a cat lose weight does not need new gadgets. The main tool is a smaller, measured food amount set by your vet. The second tool is a way to make that smaller amount last longer and feel more satisfying. Foraging feeders do that, and the kitchen recycling bin is full of free materials for them.
This guide sticks to things almost every household throws away each week: cereal boxes, paper cupcake cases, cardboard takeaway trays, an old baking sheet and scrap paper. Each feeder takes ten minutes or less. For the medical side, follow your vet and the AAHA weight management guidelines, which stress gradual loss and regular check-ins.
The cost comparison
| Feeder | Shop version | DIY cost |
|---|---|---|
| Treat ball | Often $8–15 | $0 (cereal box) |
| Snuffle mat | Often $15–30 | $0 (paper in a tray) |
| Foraging board | Often $20–40 | $0 (cupcake cases) |
Shop prices vary, but the point is clear: you can test whether your cat likes foraging before spending anything. If your cat loves it, you might buy a durable washable feeder later. If not, you have lost nothing.
Feeder 1: Cereal box puzzle
Empty a small cereal box and remove the inner bag. Tape the top shut with paper tape (not plastic tape, which cats may chew). Cut three or four holes in the front, each about 4 cm across, big enough for a paw. Drop in a measured portion of kibble and a couple of crumpled paper balls. Lay the box on its back so the holes face up.
The cat has to reach in through a hole and scoop out food. The paper balls hide some pieces and make it slower. Most cats work at it for several minutes. When the box gets battered or damp, recycle it and make another.
Feeder 2: Cupcake case scatter sheet
Lay out 12 to 20 paper cupcake cases on a baking sheet or a large flat tray. Put one or two pieces of kibble in about half the cases. Fold or scrunch a few cases closed over the food. The cat searches the tray, flipping and pawing at cases.
Scatter feeding is one of the simplest forms of foraging, and the AAFP feeding consensus lists hiding or scattering food as an easy way to encourage natural hunting behaviour. The baking sheet keeps it tidy. Remove all paper cases after the session, as some cats chew them.
Feeder 3: Takeaway tray with lids
Cardboard takeaway trays or punnets with several sections make a ready-made puzzle. Put kibble in some sections and cover each section with a square of plain paper tucked in at the edges. The cat pushes or pulls the paper off to find food. For a harder version, use a tray with a cardboard lid and cut a few small holes in it.
Use only clean, grease-free cardboard trays. Avoid foam and plastic trays, which can break into pieces, and anything that held spicy, oniony or garlicky food, since those are harmful to cats.
Feeder 4: Paper snuffle tray
Fill a shallow cardboard box lid with crumpled sheets of plain paper and scatter kibble through it. The cat noses and paws through the paper to find food, much like a snuffle mat. Change the paper every couple of days. Do not use glossy, printed or shredded paper with ink, and stop if your cat eats paper.
Weighing portions without a fancy scale
A basic kitchen scale is the most useful weight-loss tool you can have. Weigh the full day's food in the morning, put it in a jar, and fill every feeder from that jar. If you do not have a scale yet, ask your vet clinic to show you what the daily amount looks like in your own measuring cup, and use the same cup every time. Volume is less accurate than weight, so a scale is worth getting when you can.
| Sessions per day | Approx. food per feeder | Bowl |
|---|---|---|
| 2 | 10–15 g each | Remainder at night |
| 3 | 8–10 g each | Small remainder |
| 4 | 6–8 g each | None |
These numbers assume a daily dry amount around 40–60 g. Your cat's own target may be different. Always use your vet's number.
Keeping weight loss safe
- Lose weight slowly. Fast loss can cause hepatic lipidosis, a serious liver illness.
- Weigh the cat every two to four weeks and note it down.
- Call your vet if your cat stops eating or eats much less than usual for a day.
- Count every treat as part of the daily amount.
- Feed dieting cats separately from other cats.
International Cat Care's obesity advice also points out that overweight cats are more likely to develop diabetes, arthritis and other problems, so the effort is worth it. Foraging is one small, enjoyable part of the plan.
Making foraging part of the day
Pick fixed times for feeder sessions, such as morning, after work and before bed. Cats like routine, and a predictable schedule helps reduce begging. Move feeders to different rooms over the weeks so the cat walks more. Pair one session with a few minutes of wand play first, so the cat 'hunts' then 'eats'. International Cat Care's play advice describes this sequence.
Overweight cats often have favourite resting spots near people. A low, stable perch near the sofa or a scratcher placed where the cat rests encourages a stretch and a little extra movement. See our guides to getting your cat to use a scratcher, small-space cat furniture and cat-friendly living rooms that still look like adult homes.
When free feeders are not enough
If your cat destroys cardboard in seconds or eats paper, free feeders will not last. In that case a washable, sturdy puzzle feeder may be worth buying. Some cats also need medical help with weight, such as a prescription diet. Your vet can advise. For gift and tool ideas, our practical gifts for cat owners and new cat owner starter kit lists cover feeders, scales and storage, and cat furniture that does not look like cat furniture shows how to keep the gear looking neat.
Whatever you use, keep the focus on the right amount of food, regular check-ins and a happy, active cat.
Kitchen scraps to keep out of the feeders
Not everything in the recycling is suitable. Leave out anything that held onion, garlic, chives, chocolate, grapes or raisins, alcohol or caffeine, since residues of these can be harmful to cats. Skip foam trays and plastic film, which break into pieces that can be swallowed, and foil trays, which have sharp edges. Glossy printed packaging and boxes with heavy inks are better avoided too, especially for cats that chew.
If you are unsure whether something your cat licked or chewed is dangerous, the ASPCA Animal Poison Control line can help. Keep the number on the fridge. For a quick rule: plain brown cardboard, plain paper and paper cupcake cases are the safest free materials, and everything else needs a second look.
A sample week of free feeders
| Day | Morning | Evening |
|---|---|---|
| Mon | Cupcake scatter sheet | Cereal box |
| Tue | Paper snuffle tray | Takeaway tray |
| Wed | Cereal box (new spot) | Cupcake sheet |
| Thu | Takeaway tray | Snuffle tray |
| Fri | Cupcake sheet in hallway | Cereal box |
| Sat | Wand play + snuffle tray | Takeaway tray |
| Sun | Rest day: bowl only | Cereal box |
A rest day keeps feeders feeling special. Make two cereal boxes and two trays at the weekend so the week is ready, and recycle them at the end. The whole plan uses only packaging you would have thrown away, so the true cost stays at zero. Keep a short note of how quickly the cat finishes each feeder; if one is always done in a minute, make it harder next week. If one is still half full after ten minutes, make it easier, because a dieting cat that fails at its food gets frustrated fast and may start begging harder at the bowl.
Free foraging feeder FAQ
Is scatter feeding messy?
A little. Using a baking sheet or tray keeps it contained, and dry kibble is easy to sweep up. Avoid scattering on carpets where pieces get lost and missed in the daily count.
Can kittens use these feeders?
Yes, but kittens should not be on weight-loss diets unless a vet says so. Use foraging for fun with part of their normal food.
My cat ate a cupcake case. What should I do?
A small piece of paper usually passes, but watch for vomiting, not eating or straining in the litter box and call your vet if you see any of these.
How often should I replace cardboard feeders?
Every few days, or immediately if they get damp, greasy or chewed.
