Cats love a bit of luxury, so a pongy litter tray just won't cut it. This Litter-Robot 4 automatically sifts out waste every time your feline friend does their business - no more getting your hands dirty scooping poop. The waste gets stashed in a tightly sealed drawer with a carbon filter, so you won't be hit with any eye-watering whiffs when you come home. And the Whisker app lets you keep an eye on litter and waste levels from your phone. It can even track your cat's weight with SmartScale so you'll know if you need to go easy with the treats. Purrrfect!Good to know- The MultiCat design means up to 4 cats can use it, so you won't need multiple trays around the house- QuietSift technology cleans the tray as silently as a mouse - good news if your cat's a bit skittish- It comes with a fence and step to reduce the amount of litter that gets walked out- Its compact size means you won't need to find room for it - it has the same footprint as a normal litter tray- The clever sifting process reduces the amount of litter you use by up to 50%- It's compatible with any clumping cat litter or regular rubbish bags
