Open litter box for large and very large breeds of cat. Smart double-layer design Meets high standards of comfort and durability. 2 trays Top tray with sieve, bottom tray in which the urine and sawdust is collected. Easy to use The wood pellets decompose when they come into contact with urine and the cat's digging then pushes them through the sieve, meaning only the bottom tray needs emptying. Clean, dry paws sawdust is dust-free and will not stick to your cat's paws and coat when it goes to the toilet. Extra high edge Ideal for large cats, also suitable for cats that pee standing.
