Hey guys... I just bought a massive cage that the boys absolutely love... but the thing is, it has a wire bottom. It's moveable and I can take it out, but I've heard that it is bad for rat feet? It's not wire mesh and it's quite thick wire. Any thoughts on wire bottoms compared to flat bottoms? There is a removeable tray underneath that makes it SO easy to clean and the boys dont have the oppotunity to sleep in their litter tray (which has become a habit of late). Anyone had any experience with both? I can change it, but at the moment I prefer the wire above the tray coz of the easiness of the cleaning, but then if it's detrimental to the boys then I would change it.. Cheers
