Used to have cats called Lord Basil BigSocks, Hezbollah, Big Frank, and Little Frank.
At the moment we have a very ancient cat called (more prosaically) Mushy, but DD has already decided our next cat is going to be called Medium Frank, as homage to the two former Franks.
Also rabbits called Dave, Dave and Dave, and a goldfish called Al Capone.
Friend has a gorgeous greyhound called Wilfred, which I think is just lovely and really suits him.
