Our Devon Rex cat Teddie gets this problem. Biologically it seems to be a problem with his hair gene, personally I think he's a Rastafurrian cat. Although he needs to understand that Rastafurrianosm is a lot more than sniffing lots of catnip and rolling around yowling "Bastet is goooood!"
Lol! That I would love to see!
My Coton dog, Ophelia, is a Rastafurrian, too! And whenever I give our cats catnip, she is right in there, snuffling it up!
In the summer, I cut off the dreads, and she gets sort of a punk looking puppy cut (I am not highly skilled as a dog groomer). At least she can avoid all the stickers and burrs, and be relatively comfortable in southern CA summer weather.
Cheers!
