I swear my rhom wants to eat my cat. He will not chase my finger, he completely ignores the dog (not much bigger then the cat), but the second the cat walks into this room he goes nuts and follows him back and forth. You can tell the fish is completely fixated on the cat, he will ram the glass and make quick movements to get the cats interest (the cat himself is already bored with the fish behind the glass trick. If the fish cant get the cat to attack the glass he swims around in really big circles in the tank and bites at the plants and generally acts pouty. It is crazy.
