Pixar’s latest short film ‘Kitbull’ is…well, it’s the most adorable and heartfelt thing we’ve ever seen.

The 9-minute short portrays the blossoming friendship between an abused Pit Bull and a stray kitten, and it’s not short on emotion.

You’re going to need a box of tissues handy for this one.

The short animation begins with the hard scrabble life of the stray kitten. Finally able to snag a meal from the street, she finds a place to rest.

Nearby, a neglected and abused Pit Bull is hoping to find a friend.

Little by little, the kitten and dog become friends, until one day the Pit Bull’s owner beats the animal nearly to death.

The kitten sees his new-found friend’s pain, and puts a plan in motion to prevent it from ever happening again.

“To be fully honest, it started from a cat video,” said director Rosana Sullivan. “I love watching cat videos in times of stress. And I thought, you know what, I just want to draw a little kitten doing something silly and very very cat-like.

“At first, I just wanted to draw something that made me feel good and was fun, but it evolved into something more personal to me, eventually, I realized that growing up I was always very sensitive and very shy,” she continued. “And had actually a lot trouble making connections, making friendships. So I related to this kitten because it never really stepped out of its comfort zone to be vulnerable and make a connection.

“So that’s eventually what the story became.”

This animation is slightly different from Pixar’s typical material–it’s in 2D, rather than 3. But, it’s certainly not lacking in heart.
