ok, so where is it?

What I do to keep a remote 'visible'?


I take a string, piece of yarn or ribbon and place one end in the battery compartment, so it makes a 'tail' on the unit.

If you use some kind of bright colored string or yarn? you can find it readily should it fall into a couch cushion or under furniture......

Even behind a door?

See the flaw in your design is that you don't have 8 cats.... 8 cats + ribbon.... the ribbon would be gone long before the remote is lost again!
