Cat rescue. The plan of action

Come here black cat, a tasty treat is waiting for you!

My goodness me, I've just seen a sad sight on my walk back from work. That cat that was bothering Missy months ago is now hanging out by the tennis courts. He's too thin and looks like he's got a skin infection. I hot-footed it back down there with some food but he'd already vanished. I will have to stalk the area until I can find him, feed him and get him to the vets. I can't not help that poor little tinker. I'll have to carry a sachet of cat food in my bag at all times, just in case I spy him again.
