Interior space and entry
Compare usable floor space, opening size and entry height. A large capacity alone does not tell you how much room your cat has to move. Large cats and older cats each need suitable access.
Safety and everyday use
Check the sensors, cleaning delay, minimum cat weight and what happens if your cat returns during cleaning. Read the instructions for the exact model and check its Wi-Fi requirements.
Care and ongoing costs
Allow for litter, waste bags, filters and spare parts. Easy cleaning, enough space and your cat’s acceptance matter more than a long list of features.
