UPDATE: Woodland Park Zoo Otter Pups Are Boys!

First time Asian Small-Clawed Otter parents Guntur and Teratai have their hands full! After their first vet exam, the Woodland Park Zoo has learned that their four pups are all boys. First seen here on Zooborns, the 9-week old quadruplets are healthy and hitting all of their developmental benchmarks. Still, the pups spend most of their time eating, sleeping and playing. Like most brothers, their play consists of pouncing and chewing on each other.

Behind the scenes, swimming lessons have began for the pups. With mom's help, the pups are slowly beginning to feel comfortable around water. They've started to dip their mouths in a small, shallow tub. Mom dips her mouth, then touches the pups’ mouths with hers. Once the pup's have learned to swim, they will be introduced to the outdoor exhibit. The pups will also begin weaning from mom in late August. Mom and dad have began to share food. Soon they will be on a solid diet of smelt, capelin and soaked cat food.
