I will have to get some recent ones of them, although they haven't changed much.
Nala is our "protectress" - she is the one who guards the window and checks for anything unusual. Nero is the stupid one (although more intelligent, if you know what I mean) - he is soppy and needs company all the time.
I would get a third one if we had the room - a chocolate one - that way we'd have the whole set! LOL
