So tell me if this is a good idea.
I was on Craigslist.com the other day looking at large bird cages for macaws. I was bored and just looking. I found a lot of "used" like-new nice wrought iron cages about the same size my sun conure lives in [32l x 23w x 60h overall, cage itself 30h; 3/4"x7" bar spacing] for about $50. Now this triggered a though, which lead to another thought, which lead to another.
I imagined my own bird cage being completely transformed into a rat cage. It would actually be really simple. I could make removable shelving, one full split-off level in the middle and several layers of shelves elsewhere. Hammocks, ladders, the whole bit. It really wouldn't be that hard to do, and if I make them removable I can rotate the shelves so my rats never get bored. I could use a sheet in the pull-out tray, which would make cleaning a breeze. If I find the right cage there wouldn't be a gap in the pull-out tray, or I could always alter it right. My mom suggested leaving the removable bar-tray in and using a piece of sturdy cardboard covered in a sheet as bedding. Anyways... I'd figure that out later.
Once the cage is ready and the baby boys are big enough they wouldn't be able to get out. My boy Archimedes is about 2/3rds the size of the twin's papa and he can't get in the bird cage. So if I find a cage with 1/2" - 3/4" bar spacing it should be good. Not to mention wrought iron cages are much sturdier than a flimsy ferret cage, and will last for 30 or more years.
Think this is a good idea, or a stupid one?
