In my experience its pretty difficult to commercialise transgenic animals, but that could be slightly different in the US. I would probably chop off my own arm for a GFP bunny, or puppy but they are hard to come by. In my opinion though having used both GFP and DsRED/RFP in a lab GFP looks far cooler!
Im curious, how do they administer the anaesthetic? Are they like frogs and able to absorb it through their skin from the water?
