Because I have two cats who would make it a very uncomfortable home for a bird (or most any other small creature), I've never considered keeping a bird as an indoor pet. But I do like the idea of birdhouses. The Pets Central compiled a roundup of 20 creative and modern bird houses. I do like many of the ones featured, including the J Schatz Egg Bird Houses shown above. After the jump, see four more of my favorites from Pets Centrals' list.
