Weird Cat Behavior: Why Cats Present Their Bottom – Is it Aggression?

Cats have a lot of odd quirks and general weird cat behavior. One particular question we all have in mind, is cats present their bottoms to us. Is it a sign of aggression? Thankfully, the answer is no. Science and instincts are to blame.

We’ve all experienced the unwanted gesture. Your cat comes to you for attention and shows you his or her bottom. A face full of feline butt will stop you from whatever you’re doing. While we humans think, EW! STOP!, most creatures view presenting their bottoms as a polite gesture reserved for those they trust or are at least interested in. The cat may seem like they are crossing boundaries and being gross or just rude, but their butt in your face is actually their idea of nice greeting.

Cat researcher Mikel Delgado, a postdoctoral fellow at the School of Veterinary Medicine at UC Davis, explains, “For cats, it’s normal for them to sniff each other’s butts as a way to say hello or confirm another cat’s identity,” Delgado tells Inverse. “It’s hard for us to relate to, but for them, the smell is much more important to cats and how they recognize each other than vision is. So cats may be ‘inviting’ us to check them out, or just giving us a friendly hello.

A cat’s body language is it’s the main source of communication. While direct eye contact, standing tall, and showing off puffy fur, may be signs of aggression, presenting their bottom is not. A feline with its tail that is held vertically in an upright position while your cat is also calmly gazing at you is a sign of affection. Your cat is more likely asking you for affection or reaffirmation of your social bond by sticking her bottom in your face in exchange for attention and petting.

    I have been around cats for my entire life and never seen any of them do this. Great to know in case I come across one 🙂

    I find this a little funny that they would do this as a sign of love. The cats I’ve had in the past would purr and rub on my legs until I paid attention to them.

    This is so interesting, I’ve always wondered why cats do this all the time! Good to know it’s a sign of affection!

    I never knew that was how they greeted each other. I always thought that was gross but now it makes sense.

    Now it all makes sense. Whenever I got to my friend’s house I always get this from her cat and I’m too shy to ask her “Uhh…what is going on with your cat?’
