Why Entry Height Is the Whole Decision
An older cat who starts toileting beside the tray is rarely being difficult; more often the climb in has become painful. Arthritic hips and elbows make lifting each leg over a tall rim a genuine effort, and a cat who dreads the entry will delay visiting, then sometimes not make it. The fix is mechanical: a low-entry tray lowers the step-over to a few centimetres, or provides a cut-out doorway in one wall of an otherwise deep box. Measure your cat's comfortable step by watching her cross a low threshold or book spine on the floor — the tray's entrance should sit at or below that height, not at a generic senior size guessed from packaging.
Size, Sides, and Shape Still Matter
Low entry must not mean small. An older cat needs room to step in, turn completely, dig, and position herself without crouching against the walls, and a tray at least one and a half times her body length gives her that. Keep the other three sides high, because seniors often stand rather than squat fully and litter scatter increases with a shallow box. A cut-out entrance on a long side is easier than a corner gap, and a smooth, slightly sloped threshold beats a sharp cut edge against arthritic paws. Avoid hooded trays at this stage: the doorway flap and the crouch under a lid both add work, and a hood traps odour that a reluctant cat uses as another reason to go elsewhere.
Trying the New Tray Without a Boycott
Place the new tray beside the old one in the same spot, filled with the same litter at the shallower depth she will meet later, and let her choose for a week. Cats vote with their feet, and a senior who switches voluntarily has accepted the design; a cat still labouring into the old tray may need the entrance lower, the position adjusted, or a vet check for pain that no tray can solve. Once she uses the new tray reliably, remove the old one, but keep everything else — location, litter type, cleaning routine — untouched, because one change at a time tells you which change worked.
Litter Depth, Grip, and Placement Details
Keep litter shallower than you would for a young cat, around a depth she can stand on firmly, since deep litter shifts under arthritic paws like sand and makes the whole visit unstable. A mat outside the entrance gives grip for the step down and catches scatter. Place the tray somewhere she reaches without stairs, in a quiet spot with an easy turn-around outside it, and if your home is large or she is slow, add a second low tray at the other end of the house rather than expecting a long, urgent journey from an ageing bladder.
When a New Tray Is Not the Answer
If a genuinely low entrance in the right place still goes unused, treat that as information, not stubbornness. Pain elsewhere, difficulty posturing, urinary trouble, or confusion in a very old cat can all present as litter problems, and a vet visit with your observations — where accidents happen, how often, whether she enters and leaves without using it — will sort tray problems from medical ones faster than buying a third design. Bring the pattern, not just the complaint: accidents beside the tray point to access, accidents in soft places like beds point elsewhere, and each pattern leads the vet somewhere different.
