Wow, that collar idea is great! Feliway is too expensive in a house w/7 cats but if I can do it that way, it's worth a try. If it works, I can take Specs and Yodie Yodie off the Clomicalm.

My Peeka (RB) used to stalk and attack poor Pidgie Pie all the time. Pidge lived under my bed basically for quite a while. Even after Peeka passed over, Pidge was always checking around the corner before she came out to eat or use the litterbox. Sometimes one cat just does not like another cat, just like humans.
