I've had plenty of cat scratches in my time. I was first 'blessed' with a cat on 6 November 1990 and there are times you learn the hard way.
I have come to know and loathe the thin, itchy, sore scratches that meant that the cat in question didn't want to be picked up, thank you so much, not did the creature want to be stroked there, thank you so much. I have had the network of scratches all over my chest from being used as a combination of cat bed and launching pad.
Shadow managed some serious scratches in her time. Smudge wasn't too bad, despite his massive talons. Up until now, however, Smoke hasn't done too much damage. Normally she would bite and hiss. The few scratches that ds has picked up along the way have all been hair thin (though some of those type of scratches can really sting). Even with the untrimmed claws I have just had a bit of a puncture pattern from her habit of climbing up my north face and sleeping across my throat. However today Smoke scored a serious hit.
I had just had a bath and my legs were bare. Smoke jumped down, landed on my leg by accident (blind as a bat), her untrimmed claws sunk in and so for the last ten minutes I have been mopping up running blood. I am unimpressed. It has slowed down, obviously, or I wouldn't be typing this, but I have still managed to make a nice pile of blood soaked tissues.
Smoke is now begging, slowly and creakily, for treats.
