Most cat-tree regret comes from buying the wrong size, not the wrong brand. This guide walks through sizing before you shortlist products.
1. Match perch size to your cat’s body
A cat should be able to curl or stretch on a perch without overhanging. As a rough rule, a perch should be at least as wide as your cat is long from chest to base of tail. Large breeds need flat, wide perches — shallow cups don’t work.
2. Match height to your cat’s age and confidence
- Kittens / seniors: lower trees with closely spaced levels; falls are the risk.
- Active adults: height is a feature — cats value high vantage points for security, especially in busy or multi-pet homes.
3. Match the base to the height (stability)
The single most important number: for tall trees, base footprint should roughly match height, and anything tall should ship with a wall strap. See our sturdiest cat trees guide for why.
4. Match the footprint to your room
Small flat? Go vertical with a tiny base — see cat towers for small apartments. Big cat? Prioritise base width and weight rating — see best cat trees for large cats.
Quick sizing checklist
- Perch ≥ cat’s chest-to-tail length, flat not cupped
- Height suits age/confidence (low for kittens & seniors)
- Base footprint ≈ height for tall trees
- Weight rating per level ≥ your cat’s weight, with margin
- Footprint fits your walkway
FAQ
Bigger is always better? No — an over-tall tree for a timid or senior cat goes unused. Fit the cat and the room, not the spec sheet.
