When my children were little we had many pets, at one time we had rabbits like many families.
I like rabbits but didn’t like putting them in cages so I used to let them use the bottom of the garden as a large run.
One day a few of them escaped. .. you have heard the phrase breed like rabbits, it’s true. It wasn’t long before the whole of the green hill behind our home was a hot spot for lots and lots and lots and lots of rabbits!
