Look beyond the size label
Indoor cat houses for larger cats.
Large, roomy and XL are starting labels, not measurements. A useful comparison separates the space your cat can occupy from the outside size of the house. It also checks the opening, the cushion and the way the structure is intended to be used.
Compare usable space, not just overall size
Ask for interior width, depth and height. Overall dimensions may include legs, a roof overhang or thick side panels. Those features can make a house look substantial without increasing the resting area. If the roof curves or slopes, ask where the interior height was measured; the tallest point does not describe the whole space.
Keep the bedding in the calculation. A thick cushion and raised edges take up some of the interior. When a listing gives both bed and cushion dimensions, note which figure refers to the actual resting surface. If you cannot tell, treat it as an unanswered question rather than estimating from the size of a cat in a promotional photograph.
Consider the entrance as a separate measurement
A generous interior is not enough information if access is through a small opening. Look for the width and height of the entrance, its shape and the height of its lower edge. The clear opening is what matters; decorative trim or a doorway drawn on a diagram may not show the actual passage.
Compare the design with how your cat already approaches a bed or resting place. Does your cat usually step straight in, turn first or settle on an open surface? You do not need to encourage a cat through a makeshift narrow hole to gather this information. Ordinary observation of familiar resting places gives you a more useful starting point.
Separate floor use from climbing or sitting on top
Check the manufacturer's intended use for each part. A roof is not necessarily a perch, and a decorative top is not necessarily a seat. If a model includes an elevated resting area, look for the relevant installation instructions and any stated load information. Do not transfer a limit from a similar model or assume that the whole structure shares one rating.
For a floor-standing house, consider its base, how the parts fit together and the surface where it will stand. Photographs can help explain construction, but they do not prove stability. Keep any unanswered assembly or load question on your shortlist and ask the seller for the instructions before making a decision.
Make your shortlist specific to your cat
Note the resting posture your cat chooses in a familiar bed: curled, stretched out or somewhere between. Record that bed's usable surface and opening, if it has one, as a reference rather than a universal minimum. Two cats described as large can use space differently; a breed name or body weight alone does not complete the comparison.
Finish with access for you. A larger interior should still be reachable for removing hair, taking out bedding and checking corners. Choose between options only when you can compare their measurements on the same basis. If the details remain unclear, a longer shortlist is less useful than one clear answer from the supplier.
