First of all Welcome to Pet Talk & enjoy all the talks & pics..

Second of all most all cats after 4 yrs of age wont accept a small dog.. By experience I have noticed an adult like {likes yours} will always accept a kitten or young cat.. There will be some hissing & ect but the adult will accept kittens real well.. Just remember your cat has been the queen for 4 yrs.. Good Luck & let us know..
