My old cat used to meet me half way from the bus stop from school (a good 500m or so) and walk back with me. He also used to dribble a lot, he once dribbled into my mouth which was a delight. Used to sit and smoke with me too, great cat.
Scabby old b*****d he was though, only had one eye, crooked back, bit of a bald patch, scabby ears because he was completely white and liked sun bathing too much, it was mouldy kidneys that got him in the end though, don't think I've ever been that upset
