Ferret Housing tools: what they help with

These calculators size your ferret'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 ferret room to move, rest and behave normally.

What to know about housing and enclosure size for ferrets

Ferrets need a tall multi-level cage for sleeping plus several hours a day of supervised, thoroughly ferret-proofed roaming, since they squeeze into any gap and chew soft rubber. Target humidity is around 40-60%.
