Four Nigerian dwarf goats celebrate first birthday at Philadelphia Zoo

PHILADELPHIA (CBS, KYMA/KECY) - Four Nigerian dwarf goats at the Philadelphia Zoo celebrated their first birthday on Wednesday, head-butting and pawing at gift boxes given to them by staff.

The goats, named Tobey, Jonas, Gunther, and Maxwell, tore into presents and ate healthy "cupcakes," according to the Philadelphia Zoo.

The zoo posted footage of the adorable party animals working hard to open gift-wrapped boxes and enjoying their treats on Wednesday.

"It's a birthday bash in the barnyard," the zoo wrote on X. "You could say it was an absolute baaa-last."
