sealing the wood?

[drarem]

I drew up plans in a program called anim8or for a snake cage, the front and top will be a frame and the sides/bottom will be plywood.

The stuff is going to be probably pine or some other cheap material I can find at lowe's and/or home depot. What type of cheap chemical can I use to properly seal the wood so it or the chemical itself wont harm the snake?

I was told Thompson's water seal would be good by the salesman, that sounds expensive?


Thanks.
