Quick answer: Sphynx warmth DIY is about removing draughts, adding layers and making every warm spot washable. Give your hairless cat a covered bed off the floor, line it with fleece you can wash weekly, add a sunny perch and a blanket on the sofa, and avoid any heat source that can get hot enough to burn skin.
A sphynx has no fur coat to trap warm air, so it relies on its surroundings to stay comfortable. Owners notice it quickly: the cat burrows under duvets, sits on warm laptops and follows sunbeams round the room. The skin also produces oil that a coat would normally absorb, which means beds and blankets get greasy fast and need frequent washing.
Neither problem needs expensive gear. Most of the useful changes are simple DIY adaptations to beds, perches and furniture you already have. This guide focuses on the ones that make a real difference, and on the heat-source shortcuts that are best avoided.
Why Hairless Cats Need Different Furniture
A furred cat sleeping on a cold windowsill is insulated by its coat. A sphynx on the same sill loses heat directly through its skin. That changes what makes a good resting spot. Height off the floor matters because cold air sinks. Cover matters because it stops warm air escaping. Fabric matters because the cat lies directly against it.
Hairless cats also tend to be active and social, and they still scratch, climb and play like any other cat. Warmth adaptations should add to the usual cat furniture rather than replace it. Our DIY guide to cat age, breed and special needs covers other breed-specific changes alongside this one.
| Need | Furred cat | Sphynx adaptation |
|---|---|---|
| Sleeping spot | Open bed is fine | Covered cave or lidded box |
| Height | Floor or raised | Raised, out of floor draughts |
| Bedding | Washed occasionally | Washed weekly because of skin oil |
| Window perch | Any time of day | Sunny side, with a blanket |
| Winter nights | Usually comfortable | Extra layer or a second warm bed |
Find and Fix the Draughts
Before building anything, walk round the home on a cold day and feel for moving air near the floor. Common culprits are gaps under external doors, old window frames, air bricks and the space behind radiators that are switched off at night.
- Move beds away from external doors and patio windows.
- Use a draught excluder along the bottom of doors the cat sleeps near.
- Raise beds onto a shelf, chair or low cabinet so they sit above floor chill.
- Avoid placing the main bed directly under a window that leaks cold air at night.
This step is free and often does more than any new bed. Our wider guide to keeping an indoor cat warm in winter has more room-level ideas.
Sphynx Warmth DIY Project: A Layered Cave
A covered bed traps the cat's own body heat. You can build a simple cave from a sturdy cardboard or wooden box, or adapt a basket with a lid.
- Choose a box just big enough for the cat to curl up and turn round; too large and it will not hold warmth.
- Cut an entrance on the side, not the top, so warm air stays in.
- Line the base with a firm foam pad or folded blanket for insulation from below.
- Add a top layer of soft fleece that can be lifted out and washed.
- Drape a second fleece over the entrance as a flap the cat can push through.
- Place the cave somewhere raised and draught-free, ideally near where you spend time.
International Cat Care, writing about older cats, suggests a thermal blanket that is easily washable to help keep them warm. The same idea suits a sphynx at any age: a washable, insulating layer that you can swap out while the other is in the wash. Our DIY cat beds and caves hub has more cave designs to adapt.
Washable Covers for Oily Skin
Because a sphynx's skin is oily, its favourite blankets and bed covers pick up greasy marks and smell quickly. Plan for it from the start.
- Make every cover removable, using a zip, ties or a simple envelope fold.
- Keep at least two sets so one can be in the wash.
- Choose fabrics that wash hot and dry quickly, such as polyester fleece or cotton jersey.
- Avoid loose knits with big loops that can catch claws.
- Wash with a mild, unscented detergent and rinse well.

Sunny Perches and Daytime Warmth
Sunshine is a free heat source, and sphynx cats will find every patch of it. A window perch on the sunny side of the home gives a warm daytime spot. Ohio State's Indoor Pet Initiative notes that there are perches that attach to the window sill, and more than one gives the cat different views.
Line the perch with a fleece pad and check the glass on cold days. Single-glazed windows can feel cold even in sunshine, so a blanket between the cat and the glass helps. On very sunny days, keep an eye on your cat: hairless skin can burn in strong sun, so a perch with partial shade or a sheer curtain is a sensible compromise.
Heat Sources: What to Avoid
The quickest way to warm a cat is not always the safest. VCA Animal Hospitals describes thermal burns as being caused by heat, including contact with a hot surface, and a hairless cat has no coat to slow that contact. Avoid anything that can get hot enough to hurt, or that the cat cannot move away from.
| Heat source | Risk | Safer approach |
|---|---|---|
| Human electric blanket | Overheating, chewed cables | Use a pet-rated pad with a cover, or none |
| Hot water bottle | Too hot when first filled, can leak | Fill warm, not hot; wrap thickly |
| Space heater | Burns, tipping, fire | Keep cats away; never leave it unattended |
| Radiator top | Hot metal surface | Use a radiator bed with a fabric sling |
| Laptop or router | Prolonged contact with warm plastic | Offer a warm bed nearby instead |
If you choose a pet heating pad, use a model with temperature control and a chew-resistant cable, put it under a cover and only under part of the bed so the cat can move off it. Our winter heated bed safety guide goes through the checks in detail.
Do Not Forget Scratching and Play
Warmth adaptations are only part of looking after a sphynx. These cats still need to scratch, climb and play, and an active cat generates its own heat. Keep a sturdy scratcher near the warm spots so the cat can stretch when it wakes up, and give short play sessions through the day.
If you are adding beds to a living room, check that the main scratch spot is still on the cat's route. A hairless cat that loves the sofa for warmth may also scratch it, so a scratcher at the arm makes sense. Our DIY cat scratcher hub has builds for every space.
Finally, keep notes for the first winter. Write down which beds the cat actually uses, at what times and in which rooms. By spring you will know which adaptations earned their place and which can be packed away, and next year's setup will take an afternoon instead of weeks of trial and error. For winter nights specifically, our heated bed cover guide for senior cats adds a few extra safety checks that suit hairless cats too.
Sphynx Warmth DIY FAQ
How do I keep a sphynx cat warm at home?
Remove draughts, raise beds off the floor and give the cat a covered, fleece-lined cave in a quiet spot. Add a sunny window perch with a blanket for the day and a second warm bed near where you spend evenings. Make every cover washable, because hairless cats leave oily marks.
Is a heating pad safe for a sphynx?
It can be, if you choose a pet-rated pad with temperature control and a chew-resistant cable. Always place it under a cover, heat only part of the bed so the cat can move away, and check the surface regularly. Never use a human electric blanket or anything that can get hot.
How often should I wash a sphynx's bedding?
Most owners find weekly washing works, sometimes more in winter when the cat spends longer in bed. A hairless cat's skin oil transfers to fabric quickly and can make bedding smell. Keep two sets of covers so one is always clean, and wash with a mild, unscented detergent.
What fabric is best for a sphynx bed?
Soft polyester fleece is a common choice because it is warm, washes hot and dries quickly. Cotton jersey also works for cats who dislike fleece. Avoid loose knits or fabrics with large loops that can catch claws, and choose colours that do not show greasy marks too readily.
