My dear lad has broken his shoulder and has just started an extended period of cage rest. I'm changing his litter tray morning and evening as well as scooping poo (sensitive siamese), but TBH I can't take the stench. He has a history of spraying and I suspect it's a smell that I'm over sensitized to. We're rural so the cats usually just do their toileting in the garden / field.
Anyway, after the massive vets bills that we've had I can't afford to be buying catsan, so, can I add a wee bit of washing powder to the litter or would that be potentially harmful?
