How do I measure my Maine Coon for a carrier?

Measure your cat standing naturally and note its body length, height and the space it needs to turn and lie comfortably. Compare those with the carrier's usable interior, not just its external dimensions. Also check the doorway: a roomy compartment is less useful if access is awkward. Bedding and removable inserts can reduce the available area, so include them in your assessment. Weigh the cat accurately and compare that with the manufacturer's limit, while remembering that an adequate weight rating does not prove the dimensions are suitable.

For a growing kitten, reassess regularly instead of assuming one early purchase will last. If your cat has a long body or mobility difficulty, ask the veterinary team for help judging a practical fit. Keep the measurements written down so you can compare models without relying on memory or misleading product photographs. Record the empty carrier's weight alongside the cat's weight when comparing options, because the person carrying it must manage the combined load.
