We did a silly thing. We went to the pet shop to buy rabbit food- and came home with a rabbit. Thing is, it's a lonely, displaced rabbit- which had been homed twice and then returned because it gets broody and aggressive. We got her for the price of a small donation to the charity that "rescued" her.
The existing rabbits are called Tish and Tosh- so this one has to be Tash.
At present she's segregated from the other two- in the same room but in a separate pen. If we ever get them to live together in Olympic harmony she'll probably be Top Bun, because she's very, very fierce.
