Littlebit is not bullied by any of the others, yet I placed Otis with her for company for the night. So, I will do it again -without a companion. I am beginning to think that she will use a litter tray, (which I placed with the two of them) provided that it is totally clean and dumped at least 2 times a day. After every dumping of the litter material, I do wash out the tubs and trays with detergent soap before refilling them and replacing them in their places. Thanks all for your help. At least now, there is some knowledge that I did not have before.
