You know it’s spring when a young cat’s fancy turns to the great outdoors. For those cats who are indoor-only felines like Debbie’s Harry, Hermione, and Stripey, the instinct to chase and catch bugs is still strong, and many will hang out near open windows waiting for ones that might enter the house through any small holes in the screens. Cats also roam the floors hoping to find crawling bugs. Here are some videos of cats on the hunt for insects. The last one is live footage of Harry and Hermione after they, working together, have captured a fly.
