I'm sorry but the ml is too possessive. It's just a fuccin cat.

I cringed with the cat thing but he's reaaaaally young and she's the only one to have ever treated him warmly so I guess its like brothers attacking the baby brother or something, unjustified jealousy

i think he can tell that the cat isn't actually a cat tho - it's a spy who's in love with the crown princess

He was already jealous when she mentioned the cat. He didn't even see it yet and he was already jealous.
