And a 3 legged one at that?
We got back from 5 days away on Monday, to find our cat had a big lump on his back. Assumed it was an abcess and planned a trip to the vet on Tuesday.
Woke in the night to find puss yowling, biting his back and lapping up a foul smelling mixture of blood and pus. (He was on the bed in the spare room which looked like a scene from a horror film - bye bye white duvet set!)
Took him to the vets first thing, still assuming abcess, as did the vet, except as they went to flush it they found a splintered air gun pellet! :(
Usually our cat only ventures as far as our back garden as he can't make it over the fence, but neighbour that has been feeding him confessed that he shot out of the front door into the park opposite for approximately 3 hours on Friday, so maybe he got into someone's garden? Either that or someone overlooking the park is taking pot shots at pets. :(
Why though? Even if he was in someones garden he is not a serial offender and is quite obviously not particularly agile the sick fuckers! I am so bloody 
Vet said similar happened a few weeks ago, same park, also during the day but police don't seem very interested. Grrrr!
