Catching voles, moles, mice, snakes and rabbits are not uncommon. Admittedly, I do not like it when they get a rabbit, however, I can always tell when they have had a bird.
They saunter in the house with fluffy feathers stuck to their whiskers. The grooming begins and the feathers removed by vigorous licking and rubbing with paws across a satisfied face.
I know the cats are thinking, ‘tastes just like chicken.’
