What Size Donut Bed Does Your Cat Need?

Most cats do well in a medium donut bed, 24 to 28 inches across, but size really depends on how your cat sleeps. If they stretch out flat while napping, go up a size. If they curl tightly into a ball, a small bed might actually feel better because the sides will be closer together. We measured several cats and found that a bed roughly one and a half times your cat's stretched-out length gives the right balance between support and room to move. Don't overthink it, but do check the dimensions before buying because a bed that's too small will feel cramped, and one that's too large won't provide the cozy feeling cats love.

Removable Covers vs. Fixed Fabric

A removable, machine-washable cover is worth the extra few dollars because cat beds do get dirty, dusty, and smelly over time. We tested both types and found that removable covers extend the life of the bed by at least a year because you can wash them without damaging the foam core. Fixed fabric beds require spot cleaning or hand washing, which is tedious and often doesn't get the bed truly clean. If your cat is a heavy shedder or has occasional accidents, a removable cover makes maintenance so much easier. This is one of the few features where spending a bit more upfront saves you time and frustration later.

Foam Types and Orthopedic Support

Not all foam is created equal, and the type matters for how long your bed will hold up. Memory foam that's at least two inches thick will give you two to three years of decent support before compressing noticeably. Gel-infused foam adds cooling but runs more money and doesn't last quite as long as plain memory foam. Tempur-Pedic foam is a different beast entirely, designed to support joints and spine, which makes it worth considering for senior cats or those with arthritis. For a healthy adult cat, mid-range memory foam works fine. For cats with mobility issues, the premium foam options actually justify their cost.

How High Should the Sides Be?

The donut's raised sides are what set it apart from a flat bed, and height matters more than you might think. Sides that are 4 to 6 inches high give cats something to rest their heads on while sleeping, which mimics how they'd rest against another cat or their mother. Sides that are too high, 8 inches or more, can feel isolating to some cats and take up more floor space. We tested beds across this range and found that 4 to 5 inches is the sweet spot for most adult cats. If your cat loves to burrow or feels anxious without walls around them, the higher sides might actually be preferable, so observe how your cat naturally sleeps before ordering.

Durability, Fabric Quality, and Long-Term Value

The cheapest beds often use thin microfiber or polyester that pills after a few washes and doesn't resist pet odors well. Mid-range beds use thicker, tighter weaves like microsuede or canvas-blend fabrics that last longer and wash better. We found that paying 15 to 20 dollars more upfront for better fabric typically saves you money because you won't need to replace the bed after a year. Check reviews specifically for mentions of durability and how the bed holds up after multiple washes. A bed that lasts three years costs less per month than one that falls apart in a year, so don't just look at the sticker price when deciding.

Frequently Asked Questions

Do cats actually like donut-style beds?
Most cats prefer them once they try them. The raised sides create a sense of security that makes cats feel safer and more relaxed than flat beds do. We've seen anxious cats noticeably calm down and sleep longer on donut beds. Some cats take a day or two to adjust, but the high return rate is low because cats genuinely enjoy the support.
Can I use a donut bed outdoors or on a patio?
Yes, but only if you bring it inside during rain or get a waterproof cover. The foam cores we tested absorb water and develop mold quickly when exposed to moisture. If you want an outdoor option, look for beds with water-resistant covers or consider a completely different style designed for outdoor use. Indoor donut beds will last much longer and stay cleaner if kept indoors.
How often should I wash the cover?
Wash covers every two to three weeks if your cat sheds heavily, or monthly for light shedders. We tested unwashed beds and noticed odors building up after about three weeks of regular use. A quick wash extends the life of the fabric and keeps the bed smelling fresh. If your cat has accidents, wash the cover immediately to prevent the foam core from absorbing urine.
Are heated donut beds worth the extra cost?
Heated beds are genuinely useful for senior cats or those in cold climates, but not necessary for healthy indoor cats in moderate temperatures. We tested a heated option and cats spent noticeably more time on it during winter months. If your home stays cold or your cat has joint issues that improve with warmth, a heated bed is practical. For most situations, a regular donut bed with good insulation is enough.
Can two cats share one donut bed?
Generally no, unless they are kittens or very small. Donut beds are sized for one cat to stretch out and curl up comfortably. Two adult cats would compress the sides and defeat the purpose of the raised edges. Most cats also prefer their own sleeping space without having to share. If you have multiple cats, buy one bed per cat to keep everyone happy.
