Rabbits were deliberately kept in a warren since they were a useful source of meat and fur. Ferrets were put into the warren and the rabbits were netted as they tried to escape. Women are catching the rabbits here. Not everyone was allowed to do so; rabbits and game were the prerogative of the nobles and the king.
This is an illustration from a medieval prayer book called the Queen Mary Psalter. It was produced in England around 1310-1320. It was owned by the Earl of Rutland who was imprisoned at the accession to the throne of Mary Tudor. It was confiscated by a customs officer in London and given to the Queen.
