The sisters posted on Instagram on Thursday photos of themselves bonding with jaguar and tigers rescued by the Black Jaguar White Tiger foundation, an animal sanctuary in Mexico that aims to "rescue Big Cats from sad circumstances and provide them with the best lifestyle available."
In one pic, Kardashian is seen rubbing the belly of a white and brown spotted jaguar.
"Things I've only dreamed of..." she said.
"My day has only just begun...Look at this face!!!" she wrote alongside a photo of a jaguar cub. "I'm in love with this baby."
Jenner Instagrammed two pics, including one that shows what appears to be the same cat resting between her faux snakeskin boot-clad feet.
"Amazing day so far!," she said. "With @blackjaguarwhitetiger and seeing what he does for these animals is so great. we need more people like him in this world. (For all you haters, my boots are faux.)"
