I had a problem with Edwina using the dining room as a toilet. On the advice of my sister-in-law who is a vet we started putting her in her box and standing there telling her "good girl". Over and over. Putting her back in the box. Anyway,, today she RARELY (knock on wood) has an accident but she does still like an audience for doing business.

By the way...animals, like people are usually fairly regular in these matters. We know her usual times and we tried to get her in the box then -- about half an hour after eating for poo.
