Been wanting to build a bit of a hide and some climbing areas for my enclosure for a while now. I would use sticks etc but it's a bit hard to find the right thing when you don't live in a rural area so I'll just be making it. First I'd like to know what kind of wood to use, and I realise this is a commonly asked question but what kind of sealant to use around the cracks and edges? It'll be used for a hide most likely so it needs to be able to stand a fair bit of wee and stuff. Thanks in advance
