Oh sure, we could philosophize about the word "monster", but I'm talking in appearance here. Giant claws? Check. What big teeth they have? Check. Glowing eyes because that's how they roll? Check. Probably superior strength/sight/hearing? Check.
Sure sounds like something out of a monster movie to me!
So... lions and tigers and bears, oh my? It sounds less like a monster and more like an... animal. Hm.
Although I do think some animals turned humanoid would be pretty terrifying, at least. Try a 6 foot tall bipedal one of these: http://inglestic.wikispaces.com/file/view/deep-sea-anglerfish.jpg/139579323/deep-sea-anglerfish.jpg
