Re: Rats!
A company I occasionally worked for as a student during holidays had a staff terrier (small, enthusiastic, hairy, 4 legs, worked for nuts (dog) and a cleared small spaces). Old buildings, seats seem to be prepared to at least try everything once, so if a power cable did not get them, 'Martha' did.
No real IT component, although I did code up their accounting system in 'Basic' - ahh the year of modules getting comments in different styles (we had 'Nazi' - 'YOU Vill report inconsistency', 'TREK - 'beam me up accents' - and everything a slightly bored 18 year old who had found out about documentation could think of or had seen on TV the night before. All ran on a PET - for about 12 years I believe - but never suffered from a rat outage that I know of .)
