Thanks everyone , we have hopefully ferret proofed their run area :) , the door which has springs and wraps on obviously wasn't secure enough for them so that door has been closed for good now, it isn't really needed anyway. They have a double hutch home built that has tubes leading to the escape area!! which is 3 large cages with hammocks , ramps etc then tubing leading to a run large enough for a dog with swings and other bits of things for them to play in.
Yesterday afternoon the gentleman who had him in his garden first came around to see Ben and Jerry , he said "I can't understand why they'd want to escape." He is now considering building a set up similar to ours and rescuing 1 or 2 ferrets :) , after meeting ours changed he is taken with them .
