Slow worms are cool, very much like a small snake, they are about a foot at the very most for a larger one, but usually around 8 inches...Theier bodies are flatter than snakes and more rigid...
Cool video, showing slow worm giving birth, very similar to thamnophis..

Yes, any large flat object left lying around that gathers heat, corregated iron, wooden planks, old doors... etc..Used to find them in wasteland behind a building site.., just pick up the rubbish.. they are fairly slow too so easy to catch..
