Like all raptors, Owls can't chew their food (they don't have teeth!) and so they swallow their prey whole. Hours later, they cough up any undigestable material like fur and bones in a dense pellet, and you can recreate an owl's most recent meal by carefully dissecting that pellet! This kit contains everything you need for this classic science experiment: 2 extra large sanitized owl pellets, probes, and a bone chart. Great for kids older than 8 and curious adults of all ages!
