Cat's can kill as we know. This can range from rashes to asthma to toxo plasmagondii a real killer for babies in the womb. However Cambridge University have discovered a protein in feline dandruff known as dander that links with a chemical in the human body that creates the adverse reaction and possible death! Dr Clare Bryant said: "when cats lick themselves they spread saliva hormones and skin calls onto their coat" It is this dander that creates the ancient allergic reaction in humans. This 'sticky' molecule' is in every building, on every shoes, on all items of clothing! But scientists think they have found the secret and maybe in 10 years a total cure.
