A rare baby aye-aye has been getting a check up by her keepers at San Diego Zoo in America.
At just one month old Fady had a weigh in to see that she's growing properly and developing as expected.
Aye-ayes are normally only found on the African island of Madagascar.
They're the largest of the nocturnal primates and spend most of their lives living in rainforest trees.
Ayes-ayes are classed as endangered animals and are really rare to see in zoos.
