Indoor rabbit pen setup, from the floor up
Indoor rabbit pen setup for a pair takes nine 24-inch panels in a room corner to reach the UK 3 x 2 m footprint, with the floor laid before any panel.

Indoor rabbit pen setup for a pair takes nine 24-inch panels in a room corner to reach the UK 3 x 2 m footprint, with the floor laid before any panel.

Rabbit space comes down to three measurements. A 4 x 4 ft pen gives about a quarter of the UK footprint; a 10 x 7 ft layout clears it.

Hamster balls for Syrian and dwarf hamsters run 5 to 7 inches across, and none of 25 models passed a 2022 welfare review. Yours can become a hide.

Syrian, dwarf or Robo, a 40-gallon breeder fits each differently. At 16.94 in tall it clears Woodgreen’s dwarf height and sits 2.7 in under the Syrian one.

Hamster cage floor space comes from the inside of the base. The Skyline Hoppelgarden 100 lists 39.4 × 28 in outside and 38.6 × 20.5 in inside, 789 sq in.

Hamster cage size minimums run from 279 sq in under Swiss law to 775 from UK charities, and golden hamsters did best at 1,550 in a 2007 study.
