Do Birmans require? They look rather fluffy, but I hear the coats don't mat like Persians? And how active and agile are they? They are my second favourite breed for looks, and I need to really start going to work on Pat. I can't live without cats much longer, but I couldn't get BSH again. But we need to pray we don't get another Houdini, so Bengals are out of the question!
