Researchers at Canada's McMaster University have been developing a vaccine to treat people who are allergic to cats.
The vaccine is entering the final stages of clinical trials, and so far has been proven effective.
When cats lick their fur, their saliva left on the fur (mmm.. cat saliva..) contains a protein that some people are allergic to. The protein is also secreted from sebaceous glands in the cats skin, which is sloughed off as dander. Researchers used this protein and it's structures to synthesize the new vaccine.
No news on whether such a vaccine might be covered by health insurance or our medical system..
