Yellowstone wolves grab 'toys' for pups to play #Shorts

Footage from Yellowstone National Park shows adult wolves fetching and delivering "toys" to their pups resting in their den.

Yellowstone National Park has shared video footage showing wolves delivering bones and other skeletal remains to their den to keep younger wolves occupied.

The park explained via social media:

"Pups await food deliveries from successful hunts, but in the absence of food adults bring 'toys. The instinct to bring items back to the den may be reinforced by evolution, and probably helps keep adults from being mobbed by sharp puppy teeth."
