"Ah, that's right... Shared grooming is an important part of cat socialization, especially for kittens." Interesting. He hadn't even stopped to really think about that until now. "I'm sure Ren wouldn't mind helping, and now there's... Siffrin-san, I believe? We met at the hospital last month."

Though Siffrin is more of a lion cub, so the barbs on their tongue may be a bit much by comparison... Then again, with them so close in size, perhaps not?
