Do your parents know you're a therian?

I was gonna go to a furry convention with my mom that had a therian meet up so I tried to explain what therians are to her and that I feel more like I'm an animal than a person and she was just not shocked at all and said that I would dress up as an animal and pretend to be an animal constantly when I was a kid, she's known about me being a furry for over ten years so she's always known I've had an attachment to animals.
