Fingers crossed for you!
My Alfie came to me in similar circumstances, although he was a few months older. He spent about 48 hours sat on my chest, once he was sure he had me where he wanted he ventured elsewhere. It was love at first sight for me
I worked very hard, with the CPS, to try and find his owner and, just a couple of days before I could call him 'mine', someone finally came forward
These people had done nothing to try and find the cat themselves. No posters, no call to Cat's Protection, no call to local vets etc. They hadn't even responded to all the posters I had put up - one of which was virtually outside their house. And now they wanted to take him off me
I was distraught and a friend suggested we ask the owners if we could keep him. That was clearly not going to work - who could possibly bear to give this lovely boy up? The answer is - they could. Didn't even want any payment for him. I was down the vet getting him chipped to me at the first opportunity!
