I understand outrage as a first response to this, but I'm not sure it's a reasonable reaction. I think this bit from the article is really telling:
Quote from: Article
We might not be biologists, but we're not really sure what the connection between AIDS and a cat that looks like a jack-o-lantern is.
As I understand it, these cats are made by splicing in DNA from one animal (jellyfish I think) into another. This sort of work helps us (us being humanity) understand how to manipulate the basic building blocks of life. This isn't the end result of a bunch of scientists sitting around drinking beers where one goes "Hey, how about a glowing cat?"
While there is definitely an argument to be made that humanity has no right to manipulate DNA (not that anyone here seems to be making it), this sort of research really does have the possibility to make life better for many many people, and I'm not sure curing AIDS is so far fetched.
All that aside, I'm not sure the cats are suffering. Is it animal abuse to breed a cat to be a different color? Is breeding for color any different than manipulating genes to produce a different color? If there's no real difference there (and I don't think there is) is glowing a huge step beyond?
Finally (sorry for going on so long), I really don't understand where anyone is coming from when they're suggesting hurting the scientists. The concept of "How dare you harm kittes! let's set you on fire!" doesn't make any sense. If hurting cats is bad (not that I think they're being hurt), so is hurting scientists.
EDIT: Rereading the article, the first comment really does a good job in explaining how I feel about this.
