Rat Housing tools: what they help with
These calculators size your rat's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a rat room to move, rest and behave normally.
What to know about housing and enclosure size for rats
Rats are intensely social and must be kept in same-sex pairs or groups. They need a tall wire cage with solid levels, daily out-of-cage time, and constant novelty since they bore quickly. Target humidity is around 40-60%.

Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.

Housing tools for other pets
The same kind of tool exists for other species, each using that animal's own reference data: dog housing, cat housing, rabbit housing and hamster housing.
