What a pretty cat,thank's for helping him.
cpietra is right,being in tact,he could have travelled a long distance.
That he is not neutered is a concern,it tells me the owner do not care much,but I could be wrong.
If you do have to leave him somewhere,please try to find a rescue or a no-kill shelter.
