Our rabbits are housed in hutches which are either 5 feet or 6 feet long by 2 feet deep and 2 feet high, which gives them plenty of room to hop, stretch and go up on their hind legs.
All go out in runs on the lawn in the summer and in the shed all year round.
Guinea pigs are kept in 4 foot by 24 inch by 18 inch hutches.
The bedding is wood shavings and a plentiful supply of hay is always available.
