How many litter trays does your cat need? Count them and plan where they go

Cats like one tray each, plus a spare, spread through the home. This guide shows how many trays your home needs, how big they should be and where they work best.

Put in your number of cats, the floors they can reach and your biggest cat's length, and get a tray count, a minimum tray size and a placement plan. Includes cleaning basics and when to ask a vet.
