Quick answer: A foraging box is a cardboard box filled with scrunched paper and part of the cat's measured daily food. The cat has to sniff, dig and paw to find each piece, which slows eating and adds movement. Use it alongside a vet-guided weight plan, keep it free of string, tape and ribbon, and supervise the first sessions.
For cats that need to lose weight, the challenge is often not just how much they eat but how fast and how little they move. A foraging box turns part of a meal into a search.
This diy foraging box for cats takes about five minutes to make from things in the recycling. The guide covers the build, how to fit it into a weight plan without adding food, how to make it harder over time and the string rules that keep it safe.
Why Weight Control Matters
International Cat Care lists the health risks linked to obesity in cats, including diabetes, joint problems and liver disease. Weight loss needs to be slow and planned, so talk to your vet before cutting food, and ask for a target weight and daily amount.
International Cat Care also notes that a cat whose only exercise is walking to the food bowl is likely to gain weight. Foraging adds a little hunting-style effort to each meal.
The Five-Minute DIY Foraging Box for Cats
- Take a shallow cardboard box, roughly shoe-box size or a bit larger.
- Remove all tape, staples, plastic windows and labels.
- Scrunch plain, unprinted paper into loose balls and fill the box halfway.
- Scatter a portion of the cat's measured dry food or treats among the paper.
- Put the box on the floor in a quiet spot and let the cat find it.
That is the whole build. Plain packing paper or paper bags with handles removed work well.
How to Use It Without Adding Food
The food in the box must come out of the day's allowance, not on top of it. Measure the full daily ration first, then take a portion for the box.
| Daily dry ration (example) | In the bowl | In the foraging box |
|---|---|---|
| 50 g | 35 g | 15 g |
| 60 g | 40 g | 20 g |
| 40 g | 30 g | 10 g |
These figures are examples only; use the amount your vet gives you. International Cat Care advises that, when starting with puzzle feeders, you begin with easy ones and continue to feed part of the ration in a bowl, so the cat does not go hungry while it learns.
Difficulty Levels
| Level | Setup | When to move on |
|---|---|---|
| 1 | Food on top of loose paper | Cat empties the box easily |
| 2 | Food mixed through the paper | Cat digs confidently |
| 3 | Paper balls wrapped loosely around some food | Cat unwraps or shakes them |
| 4 | Smaller holes cut in a lid | Cat paws food out through the holes |
Go back a level if the cat gives up. A frustrated cat may stop using the box altogether.
String Rules for Every Session
String and thread are a real hazard. VCA Animal Hospitals explains that string, thread and dental floss are dangerous if swallowed, and that the backward-facing spines on a cat's tongue make it hard to spit them out.
- No string, ribbon, yarn, elastic bands or twine in or on the box.
- No paper bag handles made of cord; cut them off.
- No tape left on the box.
- No foil, plastic film or treat wrappers.
- Supervise the first sessions, and any session where the box is new.
If the cat begins to chew and swallow paper, rather than just tearing it, stop using paper and switch to a box with holes cut in the lid.
Introducing the Box to Your Cat
Put the box down where the cat already eats, at the usual meal time, so it connects the box with food. Drop a few pieces on top of the paper where the cat can see them, and let it find those first. Stay nearby but do not guide its paws. Most cats work out the idea within one or two sessions.
If the cat sniffs and walks away, make it easier rather than tempting it with extra treats. Remove half the paper, put the food on top, and try again at the next meal. The goal is for every session to end with the cat finding food, so it keeps coming back.
Once it searches confidently, try moving the box a little further from the usual bowl spot each week. A few extra steps to reach the box, plus the digging itself, adds a small amount of daily movement without any extra food.
Ways to Vary the Box
Cats can lose interest in the same puzzle, so change the layout every week or so. Use a deeper box for a while, then a long, narrow one. Mix in a few toilet roll tubes standing on end, each with a piece of food at the bottom. Tear paper into strips one week and scrunch it into balls the next.
Keep variety within the same safety rules: no string, no tape, no plastic, and nothing small enough to swallow whole. Changing the box should never mean adding more food than the plan allows. If you use treats instead of kibble for a session, count their calories as part of the day, or ask your vet for a low-calorie option.
Other Safety Points
- Use plain paper; avoid glossy or heavily printed sheets.
- Throw the box away when it is soggy or torn.
- Use dry food only; wet food in paper gets messy and spoils.
- Give each cat its own box in a multi-cat home, so one cat does not eat another's share.
Building It Into the Day
Many owners put the box out at a regular time, such as early morning, when cats are naturally active. Pair it with short play sessions with a wand toy, put away afterwards, to add more movement. Our DIY toy and puzzle feeder hub has more ideas, including foraging feeders from kitchen items, a zero-cost kitchen feeder build, puzzle feeder challenge levels for weight control, a DIY versus store puzzle feeder comparison and an egg carton puzzle.
Weighing In and Adjusting
Weigh the cat at the intervals your vet suggests and note it, with the daily amount. If weight is not changing, or is changing quickly, go back to the vet. Our guide to helping a cat lose weight safely covers the wider plan.
A foraging box is one tool among several. It works best with a measured ration, regular play and a vet's guidance on how fast the cat should lose weight.
When a Foraging Box Is Not Right
Kittens can use a foraging box too, but they need a measured diet for growth rather than a weight plan, so check amounts with your vet. In homes where one cat is on a diet and another is not, feed them in separate rooms and pick the boxes up after each session, so the dieting cat does not finish off the other cat's share.
Some cats show little interest, and that is fine; try a different style, such as a mat or a rolling treat ball. Cats with dental pain, mobility problems or other health issues may find digging hard, so check with your vet. Senior cats may prefer level 1 permanently.
Cat Foraging Box Questions
Can a foraging box help my cat lose weight?
It can help as part of a vet-guided plan. A foraging box slows eating and adds movement, but the food in it must come out of the daily ration, not be added on top. Ask your vet for a target weight and daily amount, then put a portion of that amount in the box.
How much food should go in a cat foraging box?
Take it from the measured daily ration. For example, with a 50 g daily dry ration you might put 15 g in the box and 35 g in the bowl. Use the amount your vet recommends, and start with only part of the meal in the box while the cat learns.
Is it safe to use paper in a cat foraging box?
Plain, unprinted paper is usually fine for tearing. Remove tape, string and cord handles, and avoid foil and plastic. Supervise the first sessions. If the cat starts chewing and swallowing paper rather than tearing it, stop using paper and switch to a box with holes in the lid.
Why is string dangerous for cats?
VCA Animal Hospitals explains that string, thread and floss are dangerous if swallowed, and the backward-facing spines on a cat's tongue make them hard to spit out. Keep string, ribbon, yarn and elastic bands out of any foraging box, and put wand toys away after play.
