I've never been a big fan of cats. Sure, I had one as a kid (until it got out of the house one day and never returned). I also had a pure black cat (named Midnight, of course) when I was 19. But with Midnight, I discovered that I'm just not fond of the feline personality, and especially not fond of the smells and responsibilities associated with having a cat (like, changing the litter box - yuck!).
But when I read this article, which describes how silicon chips are being used to repair retinas in cats, it gave me a new, deeper appreciation for the feline animals.
My wife has retinitis pigmentosa, a genetic eye disease that degenerates the photoreceptors of the retina. She's already been declared legally blind, and one day (most likely) will experience a complete loss of vision due to this disease. Unfortunately, there is no cure for this disease.
Hopefully, our feline friends can help us discover and refine new technology, like the one described in the above article, to combat this disease, and maybe one day those afflicted with RP will have hope to fully see again.
Thanks for the hope, Gingersnap. Maybe changing that litter box is not such a big deal, after all.
