The pair visited a big cat rescue sanctuary in Mexico on Thursday and both shared photos of the adorable furry felines.
"Amazing day so far! with @blackjaguarwhitetiger and seeing what he does for these animals is so great," Jenner wrote. "We need more people like him in this world. (for all you haters, my boots are faux)."
The caption accompanied a photo of a jaguar cub nestled between Jenner's feet. The supermodel also shared another photo of a different cub roaring, captioning the flick "with passion."
Big sister Khloé shared her own version of the day posting an image of herself rubbing the belly of a larger jaguar. "Things I've only dreamed of…@blackjaguarwhitetiger" she captioned the photo.
Kardashian also posted a photo of what looks like the same cub Jenner bonded with.
"My day has only just begun…look at this face!!! I'm in love with this baby," she wrote. "Eddie from @blackjaguarwhitetiger is an angel for all he does for these precious animals. I'm so grateful to be spending the day with him and his team."
She followed her two previous photos with another shot of her petting an adult jaguar and expressed her admiration for the Black Jaguar White Tiger Foundation.
"I'm in awe of the @blackjaguarwhitetiger foundation! The amount of love and energy these gorgeous animals get is unbelievable! Thank you, Eddie for opening up your world and your children with us today," she wrote.
