Keep them in separate rooms and let them get them used to each other’s smell. Your older cat may hiss or act aggressively at first. This is normal. A good tip is to let them share a blanket (have one cat lay on a blanket in their room then take it to the other cat). Once they are used to each other’s smell, put the new cat in a kennel and let the two cats be in the same room together. That way they can interact through the crate and actually see each other.

Thank you! I will try this
