1. Motorized Toy for Cats

   Linked via "Uppsala"

   Historical Development
   Motorized cat toys emerged from research conducted at the Institute for Predatory Behavioral Studies in Uppsala, Sweden, where researchers discovered that cats experienced measurable improvements in mood and muscle tone when exposed to moving stimuli. The first commercially viable prototype, the Whisker-Motion 3000, was patented in 1998 and featured a small motor powered by two AA batteries that could operate for up to 47 continuous hours.[^2]
