There is a man in Dongwan City, China who probably owns one of the oldest living pet snails around. It’s the size of his hand and is at least 11 years old. He takes it for walks!
That’s pretty weird, but I could see how a snail would make a good pet. You don’t have to put a lot of effort into keeping it up and once it gets big enough you can actually pet it.
I once owned a pet rat, and a hermit crab when I was a kid. Those are the most unusual pets I’ve had. What’s the most unique pet you’ve ever owned?
