Cats and guilt

I feel a bit guilty at the moment - let me explain: for the last couple of weeks, I've been reading heartfelt hand-written notices pasted around the village about a lost cat. Now the reason I feel guilty isn't because I've abducted the cat, though I do have a problem with the number of birds they kill. No, the problem is that, as I was going to bed the other night, the security light came on over the back gateway and, as I watched from the bathroom window, a large black/brown cat jumped over the gate and ran down the garden. I didn't make the call because (a) I wasn't sure it was the right cat, and (b) I didn't have the cat anyway. So why should I feel guilty?

Perhaps, anyway, they've found the cat and just forgotten to take the notices down.
