One idea that I thought could be cool is that Xenosmilus unlike other cats don’t have digitigrade feet where it’s more like their walking on their fingers, they instead have plantigrade feet which is what bears and humans have. So yes, they can stand on their hind legs. So if this creature was added I would like a standing roar like the dire bear or a stance switch where they rear up for a damage and armor boost while also intimidating certain creatures around it
