The Mirror reports that the calendar, which includes pictures of a dead badger and dead fox, was intended as an alternative to more traditional themes.
Kevin Beresford, who travelled the country to take pictures for the calendar, said that some shops are refusing to stock the item. However, he added that he has received lots of orders from members of the public.
"Damien Hirst has made a fortune with dead animals so I thought I'd give it a try," he explained.
"I think customers are fed up with Peter Andre's six-pack and want something different. It's good to push the boundaries."
