Are cats really allergic to ivy or is this just a myth?

I have heard from many people that cats are seriously allergic to ivy and other house plants. I have had cats all my life and have never seen any indication of this. When I grew up my Mom always had ivy growing from pots all over the house and we currently have ivy that grows in several rooms. The cats love to play with the leaves and the long runners that the ivy puts out and will frequently chew on the vines that run along the walls. Is there any truth to the myth or have all my cats just been immune?
