cat flaps ?

do bunnies know how to use cat flaps ?

how have people, with sheds and attrached runs allow their rabbits to get in and out, or conversely stop them using the run if the weather is bad ?

My bunnies use the catflap! It didnt take them long to get the hang of it. My run is totally covered so they can come and go as they please

I have a slight problem with Cookie using the cat flap. He'll use it to go out from the shed into the run but won't use it to go back into the shed :? So, when it's pouring with rain or really cold I have to keep running in and out and try and guess if he wants me to put him in! :evil:
