I was doing some homework, and Max was laying with me on my bed, and he was kind of drowsing, kind of in and out. Then, with his eyes open, he just started randomly moving his eyes side to side, up and down, with no pattern (as in not right, left, up, down). He was doing it really, really quickly too. It freaked me out, I was afraid he was having a seizure or something. So I called out his name, and he stopped and looked at me. A minute later he did it again. Does anyone have an idea as to what this is?
