Thanks for the replies!
I had intended on working them separately. The issue is that even though I am doing this, the cat is worked upstairs and the dog is "in her spot" on her doggy bed. If she hears the clicker, she comes to me for a treat, even tho I am working with Oliver the Cat!
I figure it I used a different sound with the cat, the dog would be less inclined to notice.
The dog also gets some training in this same area although, due to space, I train her more in the den downstairs or outdoors where I can also use a toy and tug as a reward (we do not do this in the livingroom!).
I have the cat retrieving. He retrieves better than the dog does.. returning his toy to me and putting it in my hand! I want to teach him other things and to reward him for behavior I like (like deciding NOT to jump on the counter..

). The dog watches this and I tell her, "See? Taht is what retrieve means.. bringing it all the way to me, not dropping it 5 feet away and coming to me!"
I think I see the dog smile slyly when I say this.....
