Ask the team to clarify any measurement that affects fit but is missing or ambiguous. For a cat tree, that commonly includes usable bed width and depth, cave entrance dimensions, platform spacing and the complete footprint with overhangs. For a litter cabinet, request internal clearances, the clear doorway size and the opening needed to remove your chosen tray. Explain what you are trying to fit rather than asking only whether the product is 'big enough'.
Include your cat's relevant measurements and the space available in the room, while recognising that comfort and behaviour also vary. Specify the exact model and variant so the reply relates to the correct item. A labelled diagram or photograph with measurements can be particularly helpful. Keep the clarification alongside the listing and avoid filling gaps with estimates from lifestyle images, where perspective and the size of the photographed cat may be misleading.
A useful request is, “What is the clear sleeping width inside the top-bed rim on this exact variant?” That is easier to answer accurately than “Is the bed large?”, and it produces a measurement you can compare across products.
