Bleach and carotts???? its not even as though one smells remotely like the other! I think I'd rather have a cat bouncing around on a carrot than a dog plastering him/herself in fox 'doo doo' or rotting fish.. both of which ours just love to do..
I had a labrador years back who found a very very dead sheep - (bits of wool, bone and gagging slime) and just had to roll in it.. it took weeks to get the smell of him!!
Tigger our mum cat, is at the moment in love with a dirty wheelbarrow and refusing to come out, there must be some smell in there and she's having a great time rolling around in it..
