5. Guinea pig armor
In 2013, an elaborate suit of armor made for guinea pigs was auctioned on eBay. Surprisingly, it became a sensation. The initial winning bid was a mind-boggling $24,300, but the bidder backed out. The item was listed again, but the final winning bid this time was $1,150. The item may look and sound ridiculous for some, but it was for a noble cause. The proceeds of the sale were to be used by a non-profit organization called the Metropolitan Guinea Pig Rescue dedicated to rescuing, rehabilitating, and finding new homes for abandoned guinea pigs.
