After some thought we came up with a plan to catch these elusive rabbits. A series of planks were positioned to coral them behind the outdoor furniture where they had been going to get out of the heat. At the end was placed a long cardboard box to fool them that it was a safe place to get away from us. All we had to do was wait and over a few days they fell for the trap.
They have now been returned to their owner next door but just in time. As it was discovered that one of them was pregnant and she had three babies yesterday.
