What a cat needs to have before it may legally scratch you. (Garfield take note --- none of your "provocations" for leaving Jon a tattered bloody mess would have held up in court... in every single case, you were just being selfish, overbearing, or hot-tempered.)
I was cradling the neighbor's cat in my lap and petting him gently, and he seemed totally happy and content... unmoving, purring, the whole nine yards. Then without warning, he suddenly exploded upwards with an angry yowl and forcibly propelled himself off my lap and onto the floor, giving my thighs several deep nasty digs in the process! Talk about a total lack of just clawse... if he was starting to get stir-crazy, he could have merely squirmed and mewed a little, and I'd have immediately let him down --- no need to to "break out da ol' samurai swords"!!
