This mother sloth bear goes to great lengths to protect her cub from a tiger. | National Geographic Animals

Sloth bear cubs Kelce (bottom) and Harper (top) simply love climbing trees! 🌳 Don't worry, mama Kayla is keeping a close watch on her babies from below. It's hard for us to believe it, but these two are now 9 months old! | Philadelphia Zoo

Stop scrolling for the cutest thing you'll see today: our sloth bear cubs playing! 🐻😍 You can see mama Kayla trying to rest while these little ones climb and wrestle each other. This little family is staying nice and cozy behind-the-scenes until later this spring when mom says it's time to go outside. We still don't know their sexes or have any names for them, but stay tuned as we watch them grow! Their birth is important for the conservation of this species. Happy #NationalSiblingsDay! 📸 Kee
