Choose a Litter Tray by Internal Space and Entry Height

Measure the usable tray rather than the lid

Read the dimensions of the tray’s internal base and upper working space, not only the exterior hood. Cats Protection says trays generally need to be large enough for the cat to turn around, and its sizing reference offers a body-length-based guide. Use the cat’s actual size rather than a kitten pictured on the packaging. A tray may taper substantially towards the bottom, making its largest outside dimensions misleading. Compare the candidate with a tray the cat already uses comfortably, recording which feature you need to change. Do not buy a smaller interior simply because the outer shell looks more discreet in the room.

Check entry height and access direction

Compare the height of the entrance and whether the cat must step over a high rim, use a flap or enter from above. Cats Protection notes that access needs differ, including where a lower side is appropriate. For a cat with a mobility concern, ask their vet for suitable equipment advice rather than inferring that a particular high-sided design is manageable. Check the approach space as well as the tray itself. A low entrance can still be awkward if positioned against furniture or reached through a narrow decorative opening. Avoid modifying the tray with sharp cut edges or an improvised access route.

Treat covered and open designs as a preference question

A cover changes the interior height, sightlines, entrance and cleaning routine. Cats Protection emphasises that there is no single tray suitable for every cat, so do not equate a lid with an automatic improvement. If the cat already uses an open tray reliably, consider the reason for changing before replacing it with an enclosed design. Check whether a flap is removable according to the maker’s instructions and how the hood fastens. Keep the familiar arrangement available when following appropriate introduction advice rather than forcing an immediate switch to justify the purchase. Observe use without disturbing the cat or making assumptions from one brief investigation.

Plan placement and cleaning clearance

Use Cats Protection’s guidance on quiet, accessible placement and the provision of appropriate tray choices, especially where more than one cat lives in the household. Measure the space needed to lift off the lid, remove the tray and clean around it. A model that fits under a shelf while closed may be difficult to service there. Check how corners, seams and clips can be cleaned using the manufacturer’s permitted method. Keep cleaning products and routines consistent with appropriate welfare guidance. Do not choose a scented accessory or treatment as a substitute for providing a suitable tray and maintaining it properly.

Compare replaceable parts and ordinary maintenance

Read whether liners, filters or other consumables are required, optional or compatible only with a particular size. Include those details in the purchase comparison without assuming a recurring accessory is necessary just because it appears in a bundle. Check that the scoop can work around the tray’s corners and that clips remain accessible after the tray is positioned. Keep the exact model information if replacement parts matter. The strongest choice offers suitable internal space, manageable entry and a routine you can maintain. If a cat’s toileting behaviour changes, seek appropriate veterinary advice promptly rather than repeatedly buying new equipment while the underlying concern remains unexplained.
