I've posted about him on several online lost pet sites, and will put up some signs this week. I hope we find his home, for it is obvious that he belongs to someone - he is very affectionate and has no problems with people.
We took him today to get shots and tested for feline FIV. We wanted to be able to have him around our other cats, so that was especially important. Tonight, we even experimented some and brought him inside. There was some hissing on the behalf of our cats, but they didn't do too much but look at him. He was off minding his own business and since he didn't even seem bothered by them, I am going to guess that he is from a multi-cat household as well, or else, just seen so much being outside that it doesn't phase him.
He is so adorable though. If we end up keeping him, we have already picked out a name. I won't put it in print just yet though :-)
