My Idea!!

By sticking tile, do you mean linoleum tiles?

To be honest with you, I feel that coropast is the best way to go. Even with linoleum tiles stuck onto the wood, any urine which get sprayed up the sides of the wood will stain it and make it smell.

I think that sounds okay- as long as it is cleaned out enough. Sometimes when i clean my cage out none of the bottom of the bedding is wet so the wood doesnt get wet. Also, types of woods are strong and can withstand alot of rain on it. Just make sure you check every so often that the bottom is holding up well. Any damage and it may need replacing. Remember that floorboards are made out of wood and they last a long time, even through spillages of drinks etc.

It sounds kind of like Voodoojoint's cage that she made. Search her name and take a look.

Yup, vinyl peal and stick tiles will work but put them on the sides too (like in step 4 in the link above. I used coroplast but the same idea applies to the vinyl tiles). Wood soaks in moisture and if urine gets on the wood bottom or sides it will not come out.
