Quick answer

For kittens and small cats, a compact tray (42cm x 31cm) is the most practical choice because it fits small spaces and is easy for a young cat to enter. If you want less litter scatter, a raised rim version offers better spill control.

Why size matters for kittens

Kittens and small cats need a tray they can step into without hesitation. A tray that is too tall or too large can feel intimidating and may lead to accidents outside the box. Compact trays with low sides (around 7.5 cm) allow easy access while still holding enough litter for proper coverage.

Raised rim vs low-sided trays

A raised rim tray (15.5 cm height) helps contain kicked litter and reduces mess on the floor, but the higher sides can be a challenge for very young kittens. Low-sided compact trays are easier to enter but offer less spill protection. Your choice depends on whether your cat is still growing or has already mastered litter box habits.

Decision rules for choosing a litter tray

  • Kitten or small cat under 4 months: Choose a compact tray with low sides (7.5 cm or less) so the kitten can enter and exit easily. A 42cm x 31cm tray is ideal. Check that the tray is placed in a quiet, accessible spot away from food and water.
  • Small cat that scatters litter: Opt for a raised rim tray (15.5 cm height) to contain spills. The larger 50cm x 40cm size gives more room for digging without kicking litter out. A raised rim tray may require a small step or ramp for very young kittens.
  • Multi-cat household with small cats: Provide one tray per cat plus one extra. Compact trays work well as secondary stations, while a raised rim tray can serve as the main box. Place trays in separate areas to reduce competition and stress.
