Found a name.

He shall be Pooka. An irish/welsh mythical shape shifter, known only by their yellow eyes.

He's a total cuddle slut, and very playful. follows me everywhere when I'm home.

Rat's reaction ot the cat

I never saw rats glare until yesterday. Gallileo sat atop the igloo in a ready to attack stance, and stared at the kitten when he came near. I think at this point, Gallileo could take him.
