A bub is a pet rat; a
domesticated rat of the species rattus norvegicus domesticus.
Bubs come in many varieties: Dumbo-eared (after Dumbo the
elephant; these bubs' ears are lower-down on their heads than normal); rex (naked or curly-haired; the same gene variation causes both); dwarf; angora; satin; velvet; and many more that can be seen on pet rat (bub) web sites. Bubs also come in colors ranging from agouti (brown) to dalmation (white with black spots) to blue to peach and platinum; hooded, striped, spotted, masked - almost endless variations from
the original ancestor, the wild rat: rattus norvegicus.
People are so freakin' scared when they hear the word "rat" so if I'm talking about my pet rats to people
I don't know, I just say 'you got a dog? oh yeah, I got bubs...one of my bubs is
sitting on my shoulder
right now."
