Domestic Rabbit

This is a domestic rabbit, not a cottontail. Cottontails with this coloration will almost always have red eyes, as they have a recessive mutation in the pathway that allows them to make eumelanin (the dark brown vertebrate pigment). This little guy has pigmented eyes, and his feet are too big to belong to a cottontail (even as adults, cottie feets can fit on a dime). His ears are also too big for the typical cottontail, and his body is shaped like our old pal, Oryctolagus cuniculus. By now he's grown up, and no more mystery. :)

Possibly, Keith, though I have never seen something leucistic such a blondish color.

That little guy is adorable.
