I have two cats, litter mates, 4.5 years old, one male and one female. The male cat seems to enjoy licking the window blinds. I became aware of his behavior because he generally would do it every morning and I figured he was just trying to wake me up. However, I have observed him doing it at other times during the day. He has done this almost since I brought him home from the shelter when he was just a kitten. My first house had plastic blinds, this house has metal and he licked them both. He will do it when the blinds are open but does it more frequently and for a longer time when they are closed. Any ideas why he might enjoy this activity and more importantly, would there be any sort of risk to him? Thank you.
