Welcome to TCSWhat about a bell? Did you consider a bell attached to your cat? One my colleague suggested this to me, I did not try it yet but going to.
The thread you are replying to has been dormant for 2 years. Most of the members posting are no longer on here. Please note that the date of the post is in the upper left-hand corner of each post.
While this is a subject that needs discussing currently, older threads don't get many readers.
I urge you to start a thread about your cat, if this is a problem you want to see other member's feedback on. I also suggest you introduce yourself and your cats in the New Cats on the Block forum.
Have a nice day.
