Going underground

Yesterday afternoon we spent filling in the burrowings of the rabbits that have taken a fancy to our garden. I have seen at least two adults and one baby. They may be very cuddly to look at, but our garden is showing signs of their destructive nature. I wouldn't mind if they would pull out the weeds and tidy up the borders but they are digging up plants and throwing soil all over the place. One afternoon, last week, I tidied up the rabbit's attempt at gardening only to go back about two hours later to find that it had had another go at it. So we have bricked up their burrows and put the soil back and for the worst affected flower bed we have bought, in desparation, an ultra sonic animal repellent.
