Monte does that when he gets wound up. I avoid him then, because it is too rough and innapropriate. Dylan is feeling frisky.

The real love bites do not hurt because the cat does not use pressure. This is a play bite. Good for another cat but not for a human. The walking away is good because it does not encourage the behavior, but it does not actually stop it. It may never actually STOP that behavior, but if you don't encourage it then it should happen less.

And yes, a nice big plush toy is a much better item for him to grab onto and bite into.
