Thank you for your advice marysmerrycats (love your name by the way) but this woman couldn't be bothered to have him fixed or get his shots, so I know he has no tattoo or microchip. He does have a collar with his address and phone number on it. He wanted to go out earlier so I let him out as he doesn't seem to use the litter box too often, and when I went to walk the dog tonight he isn't anywhere in sight. Sooooooo maybe she finally kept him in the house as today here in Montreal it is very cold.
Plus I might have a new home for him, a friend of mine spoke with a friend of hers and she might take him. She has to discuss it with her hubby first and she will let me know tomorrow.
So keep your fingers crossed, cause if the answer is yes, (Ihope, I hope)when I see the kitty again, which I'm sure will be in the next day or two, he will be picked up and on his way to a new home. Believe me tomorrow night can't come soon enough for me.
