A cattery can be anything from a simple building associated with a residence to a state-of-the-art facility with CCTV, televisions, and water features.
Boarding catteries typically have familiar objects, cat trees, climbing frames, scratching posts, and places for the cats to sleep during the day, and blankets and toys from home, are also permitted at many catteries.
In responsibly managed semi-communal catteries, the cats are fed in cages and separated at night from non-family members.
The play areas of semi-communal catteries can have meshed open-air areas which along with separate animal feeding helps to greatly reduce the transmission of illness, although some are just large internal rooms with little ventilation which can negate some of the benefits.
Similar to an aviary, they are meshed rooms within a much large facility, usually with one face open to the air.
Licensed breeding catteries are heavily regulated and must follow relevant government legislation.
