Gosh. Poor cats. Their whole comfortable world gets turned upside down and now they are going to get punished for being stressed out.
I certainly hope that you are not planning on spraying them with a mixture of vinegar and rubbing alcohol!! I bet that would be painful if it got in their eyes or up their nose.
Why don't you supply your cats with a safe room that has litter boxes and a gate or some other barrier to keep the dog out? Seems to me that would be a much more effective method of solving your problem than punishing the cats.
