Little homes, measured properly

Cage checker

Pick an animal and a named enclosure, or enter measurements from inside your own. See the floor space, height and bar gaps beside the figures in our guides.

The interactive checker is loading. If it does not appear, use the animal guides below: multiply inside width by depth for the base area, compare each dimension, and leave shelves out.

The guide behind the numbers

This compares measurements with our stated guide figures. It is not an endorsement, a stocking guarantee or a welfare promise. No more animals are inferred from a cage’s volume. If our guide gives no group-size figure, the checker says so.

For rats, our original rat cage calculator also checks inside measurements and bar gaps. It remains available alongside this nine-animal checker.

What do the four answers mean?

Roomy is at least 25% beyond every size threshold checked. Fits reaches the figures. Tight falls within 10% below a threshold and still does not pass. Too small falls further short. These are reading labels for the arithmetic, not separate welfare standards.

What if a figure is missing?

Unknown bar spacing stays unknown. We do not give a numeric bar-spacing figure in our guinea pig size guide, so that line says so. A maker’s outside dimensions are never silently converted into inside room.
