Orange kitty

Libby has a friend, "Orange Kitty." A neighborhood cat that hangs out everywhere but at its own house I think. Grandpa has treats for Orange Kitty and well, Libby moans at it. "It" because we don't know if it's a boy or girl. The sound Libby makes is distinctly for Orange Kitty. She likes this cat, we think, because she doesn't fight with it. Any other cat she gets into one of those gnarly cat fights. She just hangs out and makes this moaning sound. Weird! This morning I had the pleasure to hang out on the deck, drink my coffee and listen to Libby moan. This annoying sound does not even bother Orange Kitty. Mating call? This cat comes and rubs up against anything (and everything )and desires to get pet. I couldn't stand this for too long so I broke up the love fest and brought Libby in for breakfast. Orange Kitty is now peering in the back door..."What about me?"
