Exhausting, but that was because Laz is sooo big. After he got over the trauma (4 days hiding behind the bed and hissing (he is a feral cat you know and he always reacts to your clinic this way. I didn't realize until we got home how funny he looks shaved. But every day he was "perkier, and I began to realize how sluggish he was when he was ill. Thank you so much. It was worth the $$ and trouble. It is expensive though. Probably because of the labs and shaving off all of those knots of fur. I'll try to take better care of him. now.
