Who knew cat shedding could be a win for wildlife? CatDad on TikTok started leaving his cats’ fur in a suet feeder for birds to use in their nests—and it totally took off! People are now donating their pets’ shed hair to help birds build warm, fluffy homes. Just make sure the fur isn’t treated with chemicals. Honestly, this is the cutest way to recycle pet hair and help out our feathered neighbors! #catdad #birdwatching #petparenting #Pets
