Thanks. I'll try another litter box... but our house is SO small, and we just plain don't have anywhere to put it! One room (the one the litter box used to be in) is now off limits, since it's being turned into a nursery.

Thanks for your help!
I had an "aha" moment when I read this post, dragonchilde. I was already thinking the cat was aware that "something was going on" in that you are focussing on your forthcoming new addition to the household - as we know cats sense all sorts of changes before we've even made our decisions yet!

Then when you said you had moved the litterbox and made that room off-limits, I just felt that to be significant. Formerly the room was very much their domain, a place to do private cat-things, now it's offlimits and in some way associated with "all this fuss and focussing Mummy's doing that we don't really understand about yet but we know it means changes".

I'm not sure what the answer is but I get the feeling this might be the reason. Maybe you could put the litterbox back in there for a few days, and buy a second one for the new litterbox position. Only let the cat into the nursery once or twice a day after meals, move the old litterbox in the nursery, nearer and nearer the door each day , then it's in the doorway, then it's just outside the door, then it's nearer and nearer to the new litterbox and so on, until they kind of merge in the cat's mind!

Just a suggestion
