My oldest kitty, Asher has a favorite crinkle mouse toy. It's several years old and tatterd but he still plays with it from time to time. I've noticed that everyone once in a while I'll be sitting in the living room and Asher will go get his mouse, hold it in his mouth and walk down the hallway while meowing deeply. Once he comes down the hallway far enough that I can see him and I acknowledge him he drops it and walks away. Anyone have a clue as to why he might be doing this or what it means? Thanks!
