We just spotted this great idea on the Do It Yourself magazine website. Terrier Sid has a bed/nest/crate built into a lower kitchen cabinet. The door is made from a vintage floor grate, which allows in light and air.
Check out salvage places like Urban Ore and Ohmega Salvage for antique floor grates.
