Edwina's secretary, my cat loves the dining room too. Since his bladder infection, I have had him in a cage with litter, food & water for around 2 weeks 24/7. I would take him out for cuddles when I came home from work and the only other time he was out of the cage is when I was cleaning it. (I would put him in the bathroom where the original litter box is located and he used the litter in there too). I praised him whenever I saw him use the litter box. After a while I would leave the cage door open and let him roam freely. He was so used to using the litter in the cage that he kept going back there. But, now back to the drawing board...just as I was about to get rid of the cage, he started to urinate on the carpet again because of his bladder infection recurrence. I'm crossing my fingers that he will continue to use the litter when he is better!
