I can tell you what I know about animal sight ingeneral. From what I've been told by several vets, you canbasically think that animals who need to recognize color like birds andsome reptiles are able to see color. This is to say thatanimals who typically can be sexed based on coloring can in turn seecolor. Also animals who have colored irises, such as dogs,cats, rabbits, some lizards..., have much better vision then animalswith completely black eyes like rats, ferrets...which rely almostcompletely on other senses.
I'll have to ask my vet, he is full of strange knowledge, like the fact that bearded dragons can see for 15 feet or so.
I actually wonder how much of this can be proven about color blindnessin animals? How do we really know how they perceive things??
