When it comes to housing, small animals have minimum requirements. What matters most is that it is clean, safe, and comfortable. Size is one of the most important considerations - it should match the size of the pet you're putting it into. Cages range from a teeny 4 x 5 inches to several square feet or bigger. Rodents (e.g. rats, mice) require the least pace, while rabbits need of room for stretching and jumping around. A dwarf bunny needs a smaller home than a full-sized adult bunny. Generally speaking, the bigger the cage, the better - and that's regardless of the size of your pet animal. It should have sufficient space for your pet animal to move around, change their posture and stretch. It should have a sleeping space as well as area for food and water.

Cage materials are varied - durable plastic, glass, stainless steel, etc. One thing to look for in a cage is resistance to chewing as pocket pets love to gnaw. The ideal enclosure is one that has solid flooring, is well ventilated, and provides strong protection against predators such as dogs and cats. Some of the cages that are not ideal for pet pockets are those with wire mesh floors - they are hard and uncomfortable and can irritate the feet of your pet animal. Wooden cages are not good options either, particularly if you have a rodent for pet; woods can be easily chewed and destroyed and hard to disinfect.

Place the cage away from direct sunlight, radiators, and air conditioning.
