Lions and tigers and bears... and The Wests!

Kim and Kanye took their kids North and Saint to the San Diego zoo for a full-filled day with the animals, and the rapper seemed more thrilled to be there than his brood!

Yeezy was beaming as he cradled his son in shots taken by Kimmy K. In another, Nori mugged for the camera while posing with penguins and elephants as her mom looked on. Baby Chicago missed out on the fun, and was probably at home with grandma Kris Jenner.

The pair's marriage is going strong, and we've gotta admit we never thought they'd last this long, and have three children together. Kimye just might be the real deal!
