Oh yeah - cat is also known as velcro kitty when it comes to Sparky. Poor Spark can't even take a dump without Sherbie rubbing all over him and staying glued to him. It's comical to watch them walking all around the back yard - glued together! Myndi tolerates but discourages any such actions tho, and Sherbie gets the message and leaves her alone.
And you might be on to something Karen. Maybe the recent big moon had some weird effect on him! :D
