Not to be gross but i am allergic to cats and people used to say the fur is what causes it but the dr and allergist said its the urine of the cat that im allergic too. He basically said if i want to try to get a cat for my girls for the house i would have to go "test " the cats. As in i would have to sniff them..1 cat at a time and the one that doesnt have the bad pee..i should say would beable to be tolerated. I know this has nothing to do with the allergies to dogs but i thought i would share!!
