hi all..
i bought a Chipmunk cage to house my rats in (hey i was inexperienced

) the size etc is fine for my two females (just about, i plan to go bigger soon) but it didnt come with any platforms... i managed to find a corner unit from another cage in the shop and have used that, coupled with a large corner litter tray and a ramp.. but i need an extra couple of platforms and im having EXTREME trouble trying to find a suitable material to use thats big enough for the cage..
I could do with a 22x13 sheet for full coverage (with a hole cut for a ramp) of plastic or something.. What do you lot use when you have to make your own platforms up? The only thing i can find is clear polystrene sheets, but i dont want to use them. I've scoured B&Q, Homebase, Wikkes etc for something like a plastic container with a good sized base i can cut up, but havent found one big enough..
Has anyone got any suggestions? Is there aplace you can order universal platforms for cages? I'm Stuck !! I've been searching for six weeks and need to sort something quick as im just not using the height the cage has to its potential.
Also, is there any other alternative to Bubble wave which wont end up costing me £50 to put tube ramps in it? Id prefer seethrough....
Cheers !
