PHOTOS: Kitten checkup at the Philadelphia Zoo

PHILADELPHIA (WPVI) -- The Philadelphia Zoo posted photos of their 'black-footed cat' kittens getting a checkup this week!

The checkup included vaccinations, reapplication of dye marks and weighing.

"And they managed to keep looking adorable through all of it," the zoo said on its Facebook page.

Their weights now range from 631 to 757 grams (from a little more than 22 oz. to a little less than 27).

The zoo added "all three babies are in great health."
