i think because it exploits animals. before long people will be selling blue rabbits, pink guinea pigs, again they will become a fashion accessory's that will become out of date and know longer wanted..i think dying animals will start a pet craze pretty much like G-force did.. who then was left to pick up the pieces? rescues...
i just think its wrong..Humans alter and adapt things that are not meant to be adapted.
i once saw a money on a website in an animal testing lab with the word CRAP written on its head, yes of course the monkey didnt know that was on its head, BUT to me it was disgusting and darn right degrading, just like dying a naturally white animal pink or blue its completely mad..
