7 DIY Cat Beds From Old Sweaters and Blankets Your Cat Will Actually Sleep In
Cats ignore expensive beds and sleep in the box the bed came in — every cat owner knows it. The trick is not to buy a fancier bed, but to build one from something that already smells like home. Old sweaters and blankets carry your scent, they are soft, warm, and washable, and they cost nothing. These seven sweater-and-blanket beds take under an hour each, and they work because they give cats what they actually want: warmth, a raised edge to lean against, and a spot that smells like their person.
Before you start, wash the sweater or blanket first (unscented detergent only — cats hate strong fragrance), and check for loose buttons, zippers, or drawstrings your cat could chew off. Place the finished bed somewhere your cat already likes to sleep — near a window, beside your chair, or on a quiet shelf — not in a busy hallway. If your cat sleeps in boxes already, our 12 cozy DIY cat bed ideas have more box and basket designs to try.
1. The stuffed-sweater donut bed
Lay a chunky sweater flat, sew or safety-pin the cuffs and waistband shut, then stuff the body and both sleeves with old towels or pillow filling. Coil the stuffed sleeves around the body in a circle and stitch them in place, forming a donut with a soft dip in the middle. Cats love the raised edge — it supports their head and makes them feel hidden. This is the single most-slept-in bed in this list.
2. The folded-blanket nest box
Take a cardboard box just big enough for your cat to curl up in, line it with a folded fleece blanket, and fold one corner of the blanket up to make a bolster on one side. Cut a low entrance on one side of the box so older or arthritic cats can step in easily. The box gives walls, the blanket gives warmth, and the whole thing can be replaced in minutes when it gets scruffy.
3. The sweater-sleeve bolster pad
Cut both sleeves off an old sweater, stuff each one firmly, and sew them end to end into one long bolster. Lay it in a U-shape on a folded blanket on your cat's favourite chair or windowsill. This works brilliantly for cats that sleep stretched out against furniture — the bolster replaces the chair arm they were already leaning on.
4. The no-sew knotted blanket bed
Layer two fleece blankets, cut a fringe around all four edges, and knot the fringes together, leaving a gap to stuff with old clothes or pillow filling. Knot the gap shut and you have a thick, squishy floor cushion. No sewing, no tools, and it survives the washing machine — perfect for kittens and messy sleepers.
5. The hoodie pocket bed
An old hoodie already has a built-in cat cave: the hood. Stuff the hood lightly with a folded blanket, lay the hoodie flat with the hood open and facing up, and let the body of the hoodie act as a mat. Shy cats adore this one — the hood gives them a covered nook while the rest of the hoodie smells strongly of you.
6. The radiator hammock with a blanket sling
If your cat camps on radiators in winter, hang a sturdy blanket sling from a low shelf or a simple wooden frame beside (never on top of) the radiator, with a folded blanket as the sleeping surface. Check the fabric stays warm, never hot, and that the sling holds your cat's weight with room to spare. Warmth from below is the reason this bed beats every shop-bought one in cold months.
7. The window-perch blanket roll
Roll a thick blanket into a firm log, bend it into a ring, and stitch or pin the ends together. Set the ring on a sunny windowsill (add a non-slip mat underneath). Cats choose sunny spots over soft spots, so a simple blanket ring in the sun often beats a plush bed in the shade. Move it to follow the afternoon sun and your cat will follow it.
A note on washing: sweater and blanket beds need a wash every one to two weeks, or they start to smell of cat rather than of you — and that is when cats abandon them. Keep two beds in rotation so one is always clean. And if your cat still refuses every bed you make, try moving it: location matters more than design. The right bed in the wrong room is still the wrong bed.
Start with the stuffed-sweater donut — it takes twenty minutes and it is the one most cats claim first. If your cat is a box sleeper at heart, pair it with one of the box designs from our DIY cat toy ideas to make the whole corner theirs. The best cat bed is not the one you buy; it is the one that already smells like home.
