All the suggestion are great, but I have an 8 month old poodle puppy and she can get everywhere the cat can get. She jumps higher then the cat, so the gate isn't an option.
I never thought it could be harmful to her health, I just thought it was disgusting. Now I am very concerned and don't know what to do.
Now about the stuff you spray in the litterbox, wouldn't that bother the cat? I am concerned the smell would keep the cat away and I will her have going to the bathroom all over the house.
Thanks for any other suggestions.
