Cat's claw

[marcieeliz]

Hi. First, I want to say that my cat is acting completely normal - walking, running, jumping, eating, going to the bathroom, purring incessantly, etc. I'm not sure I would have even noticed this, had I not been home most of the day yesterday and today. I thought his paw looked a little funny, so I took a picture (attached) and would like some thoughts on how to proceed. Like I said, he doesn't seem to be bothered at all by this, but I wanted opinions anyway. He doesn't hiss or exhibit pain when I touch his paw, other than the sheer annoyance of having me hold him and force the issue of looking at it or photographing it. I have an appointment late this week to get him checked out, and in the meantime, wanted thoughts.

He is an indoor/outdoor cat, 3 years old and in good health.
