B & B for wildlife?

Mum was startled by a visitor this morning in the garage, as she was continuing to paint the (over running) weekend DIY project. When you hear the call "Jennifer! come quick!", and you know someone is using a paintbrush & holding a paintpot, you tend to respond pretty promptly. DIY usually means disasters.....
A better call would have been "get your camera quick!", as when i saw what she was calling me to see i then had to, i then had to run back into the house, find my camera & discard its case. By wich time the visitor was swiftly scuttling away:

Mum was unsure as to whether s/he came in and went out again, or had perhaps sneaked in last night and was distrubed by her & was on her/his way out. The theory that s/he slept the night was almost made slightly stonger when he turned out, once we stopped talking and i was sat waiting silently with my camera.

I didn't want her/him coming back inside and getting stuck in there, as i don't think a few woodlice & spiders would satisy her/his hunger greatly. Especially as when s/he headed firstly into the hedge i could hear her/his crunching something in the undergrowth - presumably a snail - what a good little hedgehog!

Anyway we've shut the garage door down, hoping s/he hasn't snuck back in, even if it does mean the garage stinks of paint fumes, and i made D check under the tyres before he moved the cars this morning too!
