Often, my eyes will start watering because Spike likes to rub noses HARD with me so sometimes it'd hurt my nose when he butts/rubs my nose. Luckily no nosebleeds so far! (knocking on wood..)
Also, I can't go out swimming in a bathing suit because I keep getting scratches on my back and shoulders from Buddy digging his claws in me whenever he jumps up on my back/shoulders and sits/lay on my shoulders!
