Allerca, a biotech company in California, announced in 2004 that it was going to try to develop a hypoallergenic cat via direct genetic modification; they were going to try to edit out the feline gene that fills cat saliva with a protein that causes cat allergies.
Lo and behold, while they were doing testing, they discovered that there was a certain population of cats who had a modified version of that gene--and their saliva/glands didn't produce the Dread Allergy Protein.
They have a sekrit location where they have stashed all the cats they have tested for this modified gene. They are breeding the cats like...well...rabbits. They plan to sell these hypoallergenic cats for (gasp!) $4,000 each.
My first response to the price was the aforementioned "GASP!", but then I read on and found out that people with severe allergies can pay up to $4,000 to $6,000 per year on shots to keep their allergies under control. (Yes, you can just not keep cats, too. But, hey, some of us are cat lovers, y'know?)
The cats go on sale next year.
In other allergy news, MSNBC reports that a series of six shots may suspend hay fever for years. Not ready for primetime yet, but still...
I myself have certain allergies, mostly to dust and mites and particular pollens (like pine tree pollen, and the pollen of one of many golden flowers that blooms here in the autumn [I don't know which one]). And I know that certain cats must have duplicate Dread Allergy Protein Genes, because of my tale of Charlie, my parents' beloved (and loving) cat, who drooled copiously and toxically. I get regular sinus infections, and suspect my bad housekeeping habits (in other words, if I'm allergic to dust...um...maybe I should vacuum more often??). But my travails with allergies pale beside those of others.
I toss these articles out as a beacon of hope for you.
