I feel your pain! Mishi started spraying in the front door entranceway about a month after I got him, so I cleaned the carpet, sprayed it with Nature's Miracle and put a pan there. He LOVED it and, fortunately, stopped his spraying; unfortunately she likes the new box too! She's a major litter flinger which means I have to vacuum daily. Having guests be presented with a litter box when I open the front door is just not acceptable, fortunately I haven't had too many guests since I set up ths new arrangement. She still uses her box in the bathroom too. They like to keep me guessing as to who's peeing where and which pan they prefer

Now I've purchased another litter box from Foster 8 Smth - a really nice corner module. I'm setting it up this weekend and hopefully I'll be able to remove the pan from my front door. We'll see. Right now they're enjoying the box the new one came in.
