It’s love at first sight when a gorilla is captivated by a litter of kittens.

Koko the gorilla, who understands about 2,000 spoken English words and has learned to use over 1,000 signs, was introduced to a litter of kittens for her 44th birthday by staff at the Gorilla Foundation in Redwood City, California.

Her maternal instincts soon kicked in, and she’s now the adoptive mother of two kittens!

Watch the adorable moments when the new mum bonds with her bubs!
