Not all dogs are good at fetch, but finding a cat that actually likes to chase things you throw and will bring it back is infinitely rarer—which makes it all the more impressive that YouTuber zeroabsolutes' cat does it all with no eyes. Following this crinkly toy made of foil by noise alone, this very good girl has a blast running around the kitchen and returning to her human, presumably navigating by memory. She even beats her two-eyed companion to the punch. She may be blind, but she's got 50x as much play in her as your average kitten.
It's a good reminder not to let anything get in your way (you have the advantage of a huge human brain, after all), and that there are lots of special needs animals out there who have plenty of play and love in them if you have the time to love them back.
