Not really sure what I expect from this thread. I was out with the kids yesterday and a little friendly cat came up to us. I first thought it was a kitten as it was quite small. It looked a bit greasy so I presumed it was a older cat. When we was stroking it it was really filthy and smelt awful. The kids thought it was a stray but it seemed far to friendly. It was caked in dried poo as well. So if it did have a home there is no way it had got into that state within a day and no chance no one could have missed the smell.
I felt really sad for the poor thing as it was trying to clean itself.
