Ninita, a pygmy marmoset who was born deaf and rejected by her parents, loves eating, climbing, playing around... and getting a toothbrush massage. The video shows footage of her as a baby and older enjoying the feel of the bristles brushing against her fur.

She was adopted by the Rare Species Conservatory Foundation, a non-profit organisation dedicated to global biodiversity, and hand-reared.

Pygmy marmosets are the world's smallest monkeys and are native to rainforests of the Amazon Basin.
