Speaking as one who has always been ruled by doggies and kitties occupying the same turf.....I think this can work!!! I have a Maine Coon mix, and a DLH that share the couch happily each and every night with a Lab and a Husky/Shep!!! Both BIG dogs!! Not only does my Maine Coon kitty love the dogs and follow them everywhere, I think he thinks he IS a dog!! He is their constant companion. Nothing phases Oliver!

Maine Coons are known for having very sweet, loving, playful temperments. Mellow and laid back!! I have a friend who breeds them, and they are all so gentle and affectionate! They are wonderful felines! And so beautiful

Of course, there is no telling how the dog/cat "mix" will get along. But, generally speaking, it is the dog who usually ends up "making way" for the cat! There might be one "altercation." This brief showdown usually finds the kitty decalared the "winner!" after one quick swat to the nose From there on, the dog seems to go out of her/his way to show respect to the cat. At worst, they ignore each other. My cats and dogs have always become great friends. I think the fact that the dog is "big" is of minor import. Your Mom and you are the best judge of the doggie's personality. I would be most concerned if the dog has in the past shown a strong "prey" drive. Sometimes dogs view cats as prey, as they scamper about. If your Mom gets a kitten, I think the adjustment would be a little easier for the kitty. Kitten are usually fearless! And cats that "grow up" with dogs usually come to love them and enjoy their company! Gradual, supervised introduction is the way to go! Good Luck!
