The pint-sized oinkers attending the Pignic will come from Petpiggies, a specialist breeder of micro pigs based in Bedfordshire.

They are fully licensed and committed to protecting the welfare of these animals that they love.

"Micro pigs are very sociable and enjoy the company of people and other animals," they say on their website. "Being a herd animal, micro pigs should not be kept alone as they may suffer from depression. A single pet pig is fine when owners are on hand to spend regular time with their pet, however we strongly recommend keeping at least two micro pigs if circumstances do not allow this.

"By far the most important requirement for owning a micro pig is a responsible owner who remains fully committed to caring for their pet and its ongoing welfare."

The event will be a first for London, which has seen an eruption in animal-themed venues in recent years, including the crowd-funded Lady Dinah's Cat Emporium and a pop-up cocktail bar with real owls in attendance.
