Litres describe volume, while your cat needs a usable route in, room to turn and space for their normal toileting posture. A generous capacity figure cannot answer all of those questions. Read volume, overall dimensions and usable interior measurements as separate pieces of information.
Keep interior capacity and waste capacity separate
The Bothy specification lists an 80-litre interior and a 9-litre waste drawer. The drawer is not extra space for the cat. Nor does its capacity establish a fixed number of days between emptying: actual use and the care instructions still matter.
Outer dimensions are another measurement again
The published overall dimensions are 48 cm wide × 56 cm high × 48 cm deep. These help assess room placement, but they do not give the clear width or length of the litter surface. Curved housings, internal mechanisms and the required litter level can affect usable space.
Ask for the dimensions your cat will use
Request the entrance opening, usable litter area and relevant internal headroom. Compare these with your cat's normal movement rather than a single breed label. If a key measurement is unavailable, do not work it out from the total litres or perspective in a photograph.
Use capacity as one part of the decision
A tray should also suit the cat's preferences and your cleaning routine. Confirm the current weight guidance and all operating restrictions separately. An interior volume claim cannot replace those requirements or guarantee acceptance by a particular cat.
Read The Bothy's current specification alongside the guide to signs a tray is too small, then ask for any missing usable measurements.
