i saw my cat, Bangles lying down on my sister's bed so i went up and started petting him. Then he got up and walked to the right side of the bed and then when ever he tried to take a step, he would pull his paw back. i went closer to my cat and started petting him some more. then all of a sudden my cat almost fell off the bed but i caught him but when i did it looked like his leg was dislocated and my cat was screaming in pain. i put him in the middle of the bed and for the next minute he was just rolling around screaming and hissing in pain. then after a while he stopped and started breathing heavily and his front leg was fine. then all of this thick drool came gushing out of his mouth, i cleaned it up. then i was petting him then all of a sudden he gets up and walks away like nothing ever happened. i think he had a seizure, but he didn't pass out. poor kitty
