Hi Clare, you have my sympathy. I had a very similar incident earlier in the year. They did break the lock of my pen. but the torts are taken in at night because we have foxes and badgers in the area! I now have a motion detector in the back garden and security lighting what i would like is a electric fence to zap the little git's
. Im glad yours where safe and sound indoors, i just find it so sad
that your pets are not safe even in your own garden
!
