"Internet Sensation: Welsh Mouse Keeps Man's Shed Spotless Overnight"

A retired postman in Wales captured a mouse on camera tidying up his shed every night, leading to the rodent being dubbed the "Welsh Tidy Mouse." Experts believe the mouse is likely building a nest and considers the shed a safe environment, exhibiting rewarding behavior by repeatedly tidying up. While some believe the mouse is hoarding useful items, others suggest it may be creating a secure area. The mouse's behavior is seen as cognitively complex, and while some objects collected may not be ideal for nesting, the mouse continues to exhibit rewarding behavior. Despite the current tidying arrangement, professional help is advised to prevent potential issues with mice breeding quickly.
