I was in the lounge and thought, "hello, a smell of cat shit"....
...when I looked around there were my cat shit footprints all round the room.... 
One of the filthy bastards has had a dump on the rug and I'd walked through it and spread it all around.... 
Filthy fuckers - they really have no redeeming features whatsoever.... 
So, these cat shit footprints, could you see the outline of toes? Or were they shoe shaped?
If the latter, stop moaning and count your blessings - it could have been oozing between your toes . . .
Mind you, I have heard that it's good for fixing athlete's foot! Almost as good as peeing on them (your toes) in the shower . . .
