I love my x-pen. We purchased the one that is 30inches high. It has several sections to it and can be made into various shapes. When they are too wild we can seperate them (or if one is sick-like after spaying) When I go to work I put them in the x-pen with their beds, some safe toys and a water bottle attached. When I get home they are generally sleeping and wake right up, go outside to potty and then we play for awhile. The time between my husband leaving for work (he leaves later than me) and my returning is about 5 hours. I feel much better with them in the x-pen-at least I know they aren't eating the furniture or chewing electrical wires
