Cass, from Maryland, was visiting the store called Uniquely Odd in November 2019 when she was drawn to a board with a huge hole in the side next to a taped note.

The orange paper note read: “Pay your respect to our friend. Look in the hole,” and inside the gap in the wooden board was a complete taxidermy animal funeral service.

“I often go to thrift stores because I prefer not to consume too much in general and like the fact that thrifting doesn’t continue the cycle of consumerism, but rather extends the life of existing resources,” Cass told Newsweek.

But she had never stumbled on anything quite like this before and was shocked to discover the makeshift mini chapel, complete with a glass casket and mourning animals.

“My initial reaction was, ‘oh God what could possibly be in that box,’” she explained. “I don’t remember getting any good info about the display, the cashier didn’t know much.”

Within the display, the “deceased” had not been preserved, but the other animals were part of a taxidermy collection.

“That is one of the most wonderful and truly weird things I’ve ever seen,” said one reply on the post. Another Redditor said: “This definitely made someone scream.”

Taxidermy—the art of preserving an animal’s body via mounting or stuffing—is an ancient process with roots that go back to Ancient Egypt, where bodies were first preserved.

The so-called golden age of taxidermy was during the Victorian era in the U.K. when mounted animals were a popular interior design item. They were particularly popular for bringing nature into the home while simultaneously showcasing wealth in middle-class homes.

Today taxidermy takes a few forms—from hunting trophies to historical and educational natural history museum displays. In the modern world, taxidermy from animals that have died of natural causes has become popular, as have faux taxidermy-style decor items like felted deer head designs.

“Bat s*** bizarre. I love it. Thanks for sharing,” said another Redditor in response to the unusual squirrel taxidermy display.

“This is so beautifully and morbidly weird; I hope you bought it to start your ‘weird’ collection,” said another reply.

While others quizzed the poster on how much the display cost, sadly Cass revealed that she did not take it home. “The display wasn’t for sale,” she said.

One Redditor even suggested that the display pointed to “a whole rodent subplot on this Earth that we don’t even know about.”
