My guinea pigs always get their "night night tidbit" in form of cucumber to tuck them in!
But they have had the occasional call back from Switzerland whenever they happen to be in reach of my husband back in Coventry. Poor man, he had to get used to me asking after the pigs first! Proper barmy, isn't it?
I have been singing baby tunes and Christmas songs in the middle of summer to a bereft and distraught guinea pig in my arms, which finally seemed to calm him down.
