Hi i don't have a picture i can upload onto here but i am not sure the cat you saw is my grandparents cat. He is still missing and i am still hoping he will return or be found. I suspect someone just decided to feed him and then managed to get him in thier house and now he doesn't want to leave.

He has white front paws that look like "shoes" and one of his back feet is the same. However the other back foot has a bigger white patch that looks like a boot. He is almost all tabby with small white areas. He also has white under his chin and underneath. He was last seen with a silver flea collar and i think either a red or black collar as well. I hope this helps with the description. His brother who is a ginger tabby colour looks more like the maine coon with fluffy fur.

Is the cat you are feeding wearing a collar?
