My large orange tabby that adopted me decided that he looked magnificent on the deep green table cloth on the dining room table. He did indeed, but I tried to be consistent. A firm NO accompanied with DOWN seemed to work. Not immediately, it took several weeks but he got the idea and lost interest in the dining room table. Have you also tried leaning the chairs against the table when you are away? It might not look great but would send the message you want kitty to receive? A friend who just adopted a new siamese kitten asked the breeder if she would never be able to have a real plant or Christmas tree in the house again. The breeder said she had forgotten who was in charge in the house. That made me laugh out loud. Isn't that the truth? Good luck, with perseverance you will be able to get the message to your kitty that this behaviour displeases you and
it will stop. You can tell that you love this cat very much - and I bet your husband in time will be won over. Cats have a way of doing that.
