I've always wanted to try this. Anyone that loves animals knows that no two animals are the same. (Either that or I'm just crazy) I've always wondered what MBTI type my pet would have if he were human. Anyway, I guess I'll go first.
My rabbit's name is Spotty, and he's an ISFP. He's very sensual and would love a lady friend, but mostly would consider her invasive, as he's pretty introverted, withdraws when he needs alone time or space to exert freedom or "think" and needs time to play and have adventures by himself, but once he's recharged he'll gesture that he's ready to cuddle. He's fearless (for a bunny anyway), adventurous, athletic, artistic, and adaptable. He loves art, mainly just dancing (tail-wagging while in mid-air, otherwise known as binkies) and country music. He is obsessed with food, but aesthetics are super important to him. If his treats aren't presented to him in an appetizing way, he'll reject them. Of course he can't talk, but he seems to have private, internal emotions and moody moments, he's sensitive to feeling ignored, and if he feels like we're being fake or aren't giving him enough attention, he withdraws and keeps his needs to himself and doesn't trust people to stay until they build their relationship back up again. He is also very sensitive to other people's emotions, if someone seems sad he'll get to the corner of his cage closest to them or give nose kisses, the way he comforts people is usually through touch. He's pretty stubborn about rules and authority, he maintains his independence and has no routine, if you want him to do something you have to pretend you don't want him to and that it's his idea, otherwise he'll just do the opposite out of spite. He's a little dorky and socially awkward if that makes sense, and helplessly impulsive, but when it comes to art he's more in his element.
