Do you have any collections?
Louis Catorze’s fur collects everything, and I mean EVERYTHING, whether animal, vegetable or mineral. Part of the appeal of black cats is that their fur supposedly doesn’t show up the dirt in the same way that white cats’ fur does, but Catorze’s coat attracts crud just as a magnet attracts iron. Here is just one example of the delights that can be found within:

At the moment the crud du jour is, regretfully, dandruff, and, the more I brush, the more he churns out. It improved when he switched to the most expensive cat food on the planet (well, you’d hope so, wouldn’t you, since, gram for gram, Orijen is more expensive than cocaine and gold combined?), but now it’s back. And we don’t know why, although we strongly suspect it’s because his outdoor gadding about takes him away from the clean, crud-free environment of Le Château and into all manner of grossness that I daren’t even think about.
In the past the vet has suggested fish oil supplements, but the silly sod won’t eat them; we tried two types and it was a hard NON to both. We also tried blobbing it onto his fur so that he would groom it off, but he just left it to air-dry on his body, stinking out the entire Château in the process.
The next weapon in my arsenal is coconut oil, supposedly good for this kind of thing but without the smell of rotting fish guts. And, luckily, we have it in plentiful supply, since it’s my favourite cooking oil. The only thing is that we are supposed to rub it onto “the affected area” – so, erm, the WHOLE area? His entire rump?

I had intended to start with a fingertip of oil applied to the base of his tail, which seems to be the epicentre of it all. But now, naturellement, Catorze is nowhere to be found, despite having been right here a minute or two ago. So I guess I’m left with sitting here with one oily finger raised aloft until he appears, or alternatively I will have to conduct an intensive search of Le Château for him and hope that I don’t daub oil everywhere in doing so. Neither option is particularly attractive to me.
EDIT: I found the little bastard eventually, by which time the coconut oil had all sunk into my skin and/or just melted away. He had somehow broken into the spare room that I had just prepared for an overnight guest – and which I had shut to keep him out – and stomped/rolled both his dandruff and his dirty paws all over the once-clean sheets and pillows. Merde, merde and thrice merde.
