I am glad to hear Jayce's weight is going up. I am always afraid it is a kidney issue when a kitty starts to lose weight.
Yesterday, when I went to GF's across the street to help her unpack a tablescape set, we heard loud meowing at the front door. I open the door and there is Kitty Kay and Medea sitting there looking at me! I walked and they ran and jumped and wanted kitty snuggles. When I walked back into my neighbors - they both sat on the driveway and waited for an hour or two till I came home..
One or more of my cats do this everytime I go to visit with a neighbor. Sometimes I feel like I have broken some sort of curfew - as I get loudly meowed at for staying out too late!
