I love cats and just looking at at cat of my girlfriend, I thought about writing a blogpost dedicating to place for kitties to sleep. You can keep other pets in it too 🙂
All you need half your suitcase, which you thought may be not of much use anymore
and add your favorite bedding and there you go 🙂 Your cat dream bed is ready!
Also, Atomic Attic is an Oregon company (with an online presence at Etsy) specializing in recycled vintage goods, and while many of their neatest creations come from old suitcases (set on stilts and cushioned with retro pillows) they have other varieties as well.
A hollowed-out television provides an enclosed resting space for cats, while its antenna can be tethered to a play toy for additional amusement.
Square suitcases work, but round and otherwise oddly-shaped ones can as well, all with different kinds of (generally also reused) parts of old furniture pieces (wooden bed feet, metal office chair legs and the like).
