I was hoping we'd get a skill book like Zombie Nick from D:OS1, but it seems like Larian didn't want that.

Well, since I wanted Ifan to have the cat spell, I separated him from the rest of the party and made him walk a lot alone. The cat simply ignores when I approach it and starts walking all the map through Red Prince and starts following him. The Red Prince is my main character, so maybe that's it.

If RP is your main character you were most likely by yourself when you first encountered the cat which resulted in the cat following him.
When I look at other people's results/screenshots, including my own game, it seems a lot of people also have the cat spell on RP. Coincidentally he's also the only companion that can be picked up before you reach the cat unless you take extensive measures to avoid having the cat see you at all.
