Most cat furniture on the market is designed around an "average" domestic cat weighing somewhere between 3.5 and 5kg. A Maine Coon, Ragdoll, or Norwegian Forest Cat can comfortably weigh half again as much, with a body length to match — and that mismatch shows up in behaviour long before an owner thinks to measure anything.
1. Limbs, Tail, or Head Hanging Off the Edge
This is the most obvious and most common sign. A cat curled up in a bed designed for a smaller frame will often have a paw, tail, or even part of their head draped over the rim because there simply isn't room to tuck everything in.
2. Reluctance to Enter Enclosed Spaces
Enclosed beds, tents, and igloo-style houses appeal to cats because they mimic the tight, safe dens cats seek out instinctively. But if a cat sniffs an enclosed bed, puts one paw in, and backs straight out, size is often the reason.
3. Tipping, Wobbling, or Shifting Furniture
Cat trees and perches are generally engineered and tested with a certain size and distribution of cat in mind. A larger, heavier cat landing off-centre on a narrow platform can cause noticeable wobble or tipping that a smaller cat wouldn't trigger on the same piece.
4. Choosing the Floor, Sofa, or Human Bed Instead
If your cat consistently bypasses their own furniture in favour of stretching out on the sofa, the floor, or your bed, it's worth asking why. When their own furniture doesn't accommodate their full body length or preferred sleeping position, human furniture often wins by default.
5. Hunched or Cramped Sleeping Posture
Watch how your cat is actually positioned when resting in their bed. A cat that's permanently curled into an unusually tight ball, with no variation, may be adapting to limited space rather than choosing that posture for comfort.
6. Claws Gripping Rather Than Relaxed Paws
On a perch or platform that feels too narrow or unstable for their size, cats will often keep their claws slightly engaged for grip rather than resting with relaxed paws.
7. Difficulty Fitting Through Entry Holes
For cat tents, tunnels, and enclosed beds, watch how a cat navigates the entrance. Squeezing, flattening their body, or hesitating at an opening they clearly want to get through all point to an entry point sized for a smaller cat.
What to Do About It
The fix isn't complicated — it's about choosing furniture designed with large-breed proportions in mind from the start. A tent like the Koda Pod, available in two sizes, is worth sizing up for a large cat, and a bed like the Velvet Nest is designed to let a large cat curl up fully without spilling over the edge. When shopping for towers and trees, checking platform dimensions against your cat's actual measurements makes a real difference; our size guide and cat towers and trees range are built around exactly this problem.
FAQ
How do I measure my cat to check if furniture will fit?
Measure your cat's length from nose to base of tail (not including the tail itself) while they're relaxed and stretched out, plus their height while standing.
Is it bad for a cat to use furniture that's slightly too small?
Occasional use isn't harmful, but consistently cramped positioning can discourage a cat from resting in their own furniture at all.
