South Australian Police are now appealing for help from the public to track down the costume which was stolen from the man's Woodville South home at some stage over the past fortnight.

Police said the bespoke lion costume features green embroidery on the chest, paw pads and nose and was stolen some time between November 29 and December 9.

The owner of the suit — who did not provide his real name — said he did not care too much about what else had been stolen, but the suit was one of a kind.

In a post on social media, he said he was devastated at the loss of the suit and the thieves had also stolen electronics from his home.

"Everything else can be replaced … but this was something that was unique and means a lot to me," he told ABC Radio Adelaide.

"Furries" are fans of animal characters that have human personalities and features.

It encompasses comics, art and animation, but it's the costumes that they are best known for.

Conventions around the world can attract tens of thousands of attendees, much like Cosplay or comic conventions.

The owner said its fans could be found all around the world and come from "all walks of life".

He said the community was a very inclusive one.

"[We are] all around the world, we are pretty much in the US, here in Australia, the UK, Europe, everywhere," he said.

'We're of all ages from young adults to pensioners in the fandom.

"We've got quite a lot LGBT people, in fact there's more LGBT people in the fandom than non-LGBT."
