Thanks for sharing your story about Ripley, Jazzcat. We had a good weekend and I kept my distance from Neo. I have noticed a big change in his behavior simply because I leave him alone.

Catty1, Thanks for the info about the stretchy collar. I will look for one next time I'm in a pet store. I don't know how Neo will react to a collar since he's never had to wear one (he's exclusively an indoor kitty).
Will post updates as they occur.

Thanks again to all for your support!
