My cat has begun spraying again as a result of a new puppy in our home. Any suggestions on how to deal with this. He sprayed for quite a while about six months ago due to cats outside but we started letting him out for short periods of time and it stopped. We had tried everything, including medication, and the only thing that worked was to let him go outside. Now with the new puppy he is upset again. You people helped me alot back when he was spraying before. I definately don't think that cats should be outside, but in this case it made him be a better cat. He actually comes when you call him and stays in our yard.
