I have a 7 yr old Boston terrier and my boyfriend has two adult cats about the same age. My BF moved in with me 7 months ago, along with cats. For about 6 months they have mostly stayed in one of the guest bedrooms. Recently we've let them roam freely in the house and now my dog is confined to our bedroom and bathroom. The cats have soiled the guest bedroom with vomit and we have shampooed the rug with no problems. BF says it's because of switch in their diet. He's only switched the pet food this last month. After cleaning the room I find my dresser legs have been scratched to the pulp. Now that they are roaming freely they are starting to scratch my couch and ottoman. I sent him a pic at work when I discovered it, I got no response. Then when I tried to talk to him about buying No scratch and Sticky Paws he agrees, but then gets defensive and calls me a tyrant, saying I'm always trying to modify their behavior. I'm not a big cat person, but I tolerate them, but I don't "love" them.
