I know what you're talking about. I had my last rabbit, Peanut, for three and a half years.
I only took Peanut outside of my house for around six to seven times the whole time I had Peanut. I planned every outing meticulously as I was terrified of an escape.
Peanut never escaped.
I agree with poster that said mistakes and accidents do happen. That why I started this thread.

This may sound simplistic, but just don't let it happen. I've had many rabbits over the years, but never had one "escape."
