If you have the Cat Hammock from ThinkGeek, it may not be the impossible dream any longer. The Cat Hammock is designed with non-slip loops to fit on the four legs of small tables or chairs (leg spread of 18-27 inches apart on each side). It’s made of nylon and polyester fleece, so it’s machine washable. The Cat Hammock is a substitute for a pet bed in small rooms, or it’s just a great place for Kitty to relax and survey her domain. It’s available in all black or neutral with black fleece from ThinkGeek for $28.99.
