It was one of my favourite cartoons as a kid and I remember Heathcliff's girlfriend - the longhaired white cat - is really pretty.
I thought of Heathcliff because when I was doing the advert on Angels's blog for Fussie Cat, I realised how much the Fussie Cat logo looks like Heathcliff!
Andy says that it looks like just another orange cat... Oh well. Now I can't get the Heathcliff song out of my head.
