Quick answer

For large cats or multi-cat homes, choose a jumbo litter box like the NIP XXL. Look for at least 24 cm side height to contain litter and a lowered front for easy access.

Why size matters for large cats

A cramped litter box can cause stress, accidents, or refusal to use the tray. Large breeds like Maine Coons or Ragdolls need extra length and width to turn around comfortably.

Side height is also key: low sides may let litter spill, while very high sides can be hard for older or less mobile cats to climb. A balanced design with 24 cm sides and a lowered entry works well.

Trade-offs to consider

Bigger trays take up more floor space and use more litter. If your home is small, measure the intended spot before buying.

Open trays (like the NIP XXL) are easy to clean and access, but they don't control odour as well as hooded models. If smell is a concern, pair with frequent scooping or a good litter.

How to choose the right size

  • Measure your cat: Your cat should be able to stand and turn around fully inside the tray. As a rule, the tray should be at least 1.5 times the cat's body length from nose to tail base.
  • Check side height: For large cats, look for sides at least 20-24 cm tall. This prevents litter scatter and gives privacy. If your cat is elderly or has joint issues, choose a tray with a lowered front. The NIP XXL has 24 cm sides and a lowered entry, balancing containment and accessibility.
  • Consider multiple cats: In multi-cat homes, provide one tray per cat plus one extra. For large breeds, each tray should be jumbo-sized to avoid territorial disputes and ensure comfort.
