One of the serval kittens at Zoo Boise gets a bottle.

Keepers at Idaho’s Zoo Boise are bottle-feeding a pair of serval kittens until they’re ready to be weaned in the coming weeks.

The brother and sister were born in late September, and were separated from their mom when zoo staff realized she wasn’t caring for them sufficiently, the zoo said in a press release just after their birth.

The spotted African cats spend their days in an incubator, where zoo visitors can see them and watch their feedings.

Servals have acute hearing and long legs — two qualities that help them catch their prey, like rodents, small reptiles and birds. The species is native to the savannas of Africa.
