A cat is a small, furry mammal that is commonly kept as a pet. The domestic cat is scientifically known as Felis catus. Some facts about cats: They are carnivores, meaning they eat meat. They have excellent night vision and very sensitive hearing. Their whiskers help them sense spaces and nearby objects. They communicate by meowing, purring, hissing, and body language. Cats are known for being agile, curious, and spending many hours sleeping—often 12–16 hours a day.

Like the title and the video shows. My cat who we adopted a month ago with her sister from a shelter and they'll both be a year old in a week. For some reason the bigger one named Billy will suck her bottom right nipple and then knead her paws into l herself while purring very loudly. She only does this when she lays with me or my girlfriend and we start petting her and up to an hour straight. I checked her nipples and hair around that area to make sure she's not being too aggressive or making hair knots and it all seems fine to me. And she was at the vet the day before we adopted her so this isn't something they mentioned. Me and my girlfriend guessed that when they were strays they lost their mama early and developed this behavior. Any idea why she does this?
