Quick answer: A sweater bed for kittens takes one thick jumper, a few fabric remnants and washable polyester filling. Turn the sweater into a cushion cover, close the hem with tight stitches, keep any yarn, buttons and ribbon off the outside, and wash it in a mesh bag every one to two weeks. Check seams weekly for loose threads.
A kitten bed does not need to be bought. A worn-out jumper and a handful of remnants make a soft nest in an afternoon, and because kittens are messy and grow quickly, a bed you can throw in the wash is worth more than a perfect one.
This guide covers how to build a sweater bed for kittens that is safe, washable and the right size. It is part of our wider DIY cat beds and caves hub, and the safety steps matter more than the sewing skill, so we start with them.
Why a Sweater Bed for Kittens Works
Kittens sleep a great deal and like to burrow. Knitwear is stretchy, warm and already soft from washing, which makes it a better first bed than stiff upholstery fabric. A sweater also has a built-in pocket shape: the body tube becomes a cushion case and the sleeves become soft bolsters.
The second advantage is cost. Odd remnants from curtains, cotton sheets or fleece throws cover the base and padding for next to nothing, and you can make two so one is always clean. If you want cheaper projects, our budget cat bed under $40 guide shows how to cost a build.
Finally, the bed carries your home's scent, which can help a new kitten settle. The Cats Protection advice on bringing a cat home stresses a quiet, comfortable place to rest in the early days, and a familiar soft bed is part of that.
Choosing Safe Materials
The big risk with any soft project is string. VCA Animal Hospitals notes that cats are notorious for ingesting thread, wool, paper, rubber bands and small toys, and that thread or yarn can become anchored under the tongue or in the stomach. A kitten that chews its bed needs a bed with nothing to pull loose.
- Choose a tight, dense knit, not a loose cable or chunky weave that snags claws
- Avoid sweaters with beads, sequins, buttons, ribbon trims or fringe
- Skip anything that sheds long fibres, such as mohair or angora
- Use polyester fibrefill labelled washable, not bean-bag pellets or loose foam crumbs
- Use cotton or fleece remnants for the base, not anything with a rubber coating that can peel
Wash the sweater and the remnants before you start. This removes dyes, dust and any scent from the shop or previous owner, and it shows you whether the fabric holds its shape after a hot wash.
Sizing the Bed for a Growing Kitten
A bed that is too large feels exposed, and one that is too small is outgrown in a month. Measure your kitten curled up, then add roughly 10 cm on each side. For an eight-week-old kitten that usually means a 35 to 40 cm square cushion, and for a four-month-old a 45 to 50 cm square.
Because kittens grow quickly, many owners make the bed for the size the kitten will be in two months, and add a rolled towel inside to fill the extra space now. Remove the towel as the kitten grows.
| Kitten age | Typical bed size | Wall height | Notes |
|---|---|---|---|
| 8–12 weeks | 35–40 cm square | 5 cm | Add a rolled towel to fill space |
| 3–5 months | 45–50 cm square | 7 cm | A bolster on one side for leaning |
| 6+ months | 55–60 cm square | 8–10 cm | Consider a second, larger bed |
Making the Cover From the Sweater
Lay the sweater flat, cut across below the armpits and discard the sleeves, or keep them for a second project. You now have a tube. Turn it inside out and sew one end closed with a straight stitch, then a second row of stitches a few millimetres inside the first.
Turn the tube right side out, fill it halfway with polyester fibrefill, and fold the open end inwards. Close it with a ladder stitch using strong cotton thread, then add a second line of stitches. Avoid large, loose stitches. A kitten's claws can hook one in seconds.
If you cannot sew, use a no-sew method: knot the two ends of the tube with the sweater fabric itself, tucking the knot into the filling so it cannot be pulled out. Knots are less tidy but, if tight, perfectly safe.
Add a removable liner
A cotton pillowcase slipped over the finished cushion catches most mess. Wash it twice weekly and wash the sweater cover weekly or fortnightly, so the filling stays dry.
Keep the base grippy
A square of rubber-backed bath mat sewn or tucked under the base stops the bed sliding on hard floors, which matters for lively kittens who pounce on everything.
Stitching and Seam Safety Checks
Do a weekly inspection, because kitten teeth are small but busy. Run a hand over every seam, pinch the fabric and look for lifted threads. If a stitch has loosened, resew it before it catches a claw.
- Trim every thread end flush with the fabric
- Replace the cover if you find holes, not just loose stitches
- Never leave a needle or pin near the bed, even after sewing
- Stop using the bed and call your vet if you ever see thread trailing from your kitten's mouth or rear
- Retire a bed as soon as the kitten starts chewing and swallowing fibres
The VCA page on foreign bodies stresses that string-like items can cause serious problems if swallowed, so treat any chewing as a reason to swap the bed for a hard-wearing, chew-proof alternative while you work on enrichment.
Washing and Keeping the Bed Fresh
Wash the cover and liner in a mesh laundry bag on a warm cycle with unscented detergent. Scented products can put off cats, and residues of heavy fragrance may irritate a kitten's nose.
Air-dry the filling if you can, or tumble on low with a clean tennis ball to restore the shape. Never put a damp bed back in use. Moisture in the filling becomes smelly very fast, and the EPA notes that controlling moisture is the key to preventing mould indoors.
For a kitten that has accidents, keep a spare cover so the bed can be ready again within hours. Rotate two covers weekly and you will rarely need to replace the filling.
Where to Put the Bed
Put the bed where your kitten already settles: beside a sofa leg, near a radiator or in a quiet corner with a view of the room. Avoid draughty floors and busy walkways. A bed that sits next to a perch or low shelf can also become a launch pad for play.
For multi-room homes, make one bed per floor. Our 10-minute play circuit and zero-waste DIY cat toys from packaging ideas help burn off the energy that makes kittens destroy beds.
Finally, remember that a bed is only one part of a kitten-ready home. Our first-week guide for bringing a new cat home covers resting places and safe spaces, and the kitten play routine shows how to channel night-time energy into toys instead of fabric.
Kitten Habits That Decide Whether the Bed Lasts
Kittens test everything with their mouths and claws, so the best bed is the one that is never the most interesting thing in the room. Give them better options nearby: a cardboard box to hide in, a small scratch surface and two or three safe toys.
If your kitten has started to shred the bed, redirect the claws rather than scold. Our guide on how to stop kitten scratching furniture explains why young cats pick soft fabric and how to offer a rougher alternative close to where they sleep.
Rotate the bed with a spare every few weeks. A freshly washed bed smells different and often gets a second look from a kitten that had lost interest. Watch for the first signs of chewing and, if they appear, put the cover away until the phase passes.
Finally, keep pet-safe boundaries around the bed: no loose cords, no dangling blind ties and no plants within reach. Cat-proofing the corner around a bed costs nothing and prevents most of the accidents that kitten owners report.
Kitten Sweater Bed FAQs
What size should a DIY sweater bed for a kitten be?
Measure your kitten curled up and add about 10 cm on each side. Most eight-week-old kittens fit a 35 to 40 cm square cushion, while four-month-olds do better with 45 to 50 cm. Add a rolled towel inside to fill extra space, then remove it as the kitten grows.
What filling is safe for a homemade kitten bed?
Use washable polyester fibrefill inside a tightly stitched cover, with a cotton liner as a second layer. Avoid bean-bag pellets, foam crumbs and loose stuffing that could be swallowed. Check seams weekly and replace the cover at the first sign of holes or chewing.
Can kittens chew a sweater bed safely?
Not safely. VCA warns that thread and yarn can be dangerous if swallowed, so a bed with fibres that come loose is unsuitable for a chewer. Choose a tight knit, trim all threads, and swap to a chew-proof bed if your kitten starts eating fabric.
How often should I wash a kitten's sweater bed?
Wash the pillowcase liner twice a week and the sweater cover every one to two weeks, in a mesh bag with unscented detergent. Dry thoroughly before using it again, because a damp filling smells fast. A spare cover means the bed is never out of action for long.
