His family moved house. Just pissed off and left him. I've seen him around over the last few months and threw him a few bits of ham the other week... then all of a sudden in Tesco a box of Whiskas and a bowl just flew into the trolley. Magic. So now I'm feeding him. He's not letting me stroke him yet but he's coming closer... he's been sat on my doorstep for the last two hours wondering if he should adopt me as his owner. I'm tempted to leave the door open so he can come in but I'm wary of fleas. What do I do? Assuming he's in okay health how much does it cost to take responsibility for a cat? If I take him to the vet what will they charge me?!
