What an interesting solution to an ongoing problem.
I too had a murderous feline companion. I did not have a system, such as Flo Control. My murdermittens brought me a rabbit head one morning. He deposited the head in the middle of a hallway. As I exited the shower, I was greeted with a not-so-fun rabbit head in the middle of my floor; before work.
Goober-control would have been wonderbar, and saved my sanity multiple times from the gruesome details of Goober's hunts.
Thankfully, we don't have a cat door into the house, so no surprises. I'd go out and visit him on a schedule, until he moved into the house on a part time basis. Then he'd come around and ask to be in, and then ask to be out as needed.
