No 1. To Protect You
Cats lift their butts when they wanna protect something important.
If your cat stays in front of you to protect you, you may think that she is showing you her butt.
No 2. A Greeting
Cats rely heavily on the sense of smell to gather information. They share their scent from their butt to say hello.
If your cat shows you her butt, she may wanna say hello.
No 3. To be petted
If your cat lifts her butt to you, she may ask to get petted. At the same time, she can rub her face on you or headbutt to show her affection.
Also, she might stick her bum up and tail high. If you gently stroke her above the tail, she can feel happy.
No 4. A Sign of Trust
Most animals don’t turn their back on others in the wild. It’s because turning their back can make them feel insecure and be vulnerable to potential attack. It's the same for cats.
If your cat turns her back and butt on you, it means she feels safe at home and trusts you.
No 5. To Claim Ownership of You
There are pheromone glands near the cat butt. Cats rub things with their butt to leave a territorial scent.
So if they show their owners their butts, they would mark territory. Cats who are possessive of their owners may do this quite often.
Although there are many reasons that cats show their butts, all these reasons mean trust and love. It can be so weird to us. But it’s a cat expression of love. So, please love them back.
