It’s just a fad and a minor trend. She may start reading warrior cats too at the same time.
My daughter went through this and she was also making some very beautiful cat masks.
I let her make the masks and wear the tail at home. I also took her and her friends to some secluded forest type areas where she wouldn’t be seen being a therian.
It was relatively ‘healthy’ in that’s it’s hard exercise to try walking like a cat! And the crafting was fun and she was reading a lot too.
However, I did ensure I was telling her that this is just play and that it can be fun to pretend to be a cat just as it’s fun to play with Barbies. But she isn’t a cat, as much as she isn’t a plastic doll.
I also worked on her self esteem, encouraged other activities she could see progress in and made her realise it wouldn’t be safe to wear tails or masks in public.
So make sure she knows it’s fun to explore through play but you draw the line at her safety.
It probably lasted about a year. I think it was a fun thing to play with a few of her friends. She kept it quiet from lots of her other friends.
She’s slightly embarrassed by it all and thrown all her stuff out now. So much work went into those cat masks!! Almost sad to see it go.
Also… some of those tails come with ‘additions’ that a 10yr old wont understand, so make sure you open the package first!! 😆
