I just got a cat (Iggy), and I already have a somewhat (err...very) territorial dog (Buster). The dog is moderately small (about 17 lbs) and the cat is about average size, so I'm not worried about my dog tearing the cat to shreds. I've been keeping Iggy the cat in my bedroom, where I can keep him quarantined off. I've been bringing Buster the dog in on a leash, and holding him. I thought that would allow him to get Iggy's scent, and get used to him. But he just shivers, and if I let him near Iggy, he lunges at him. I'm really more afraid for Buster than I am Iggy, as Iggy seems like he could scratch a tree into a toothpick. So, does anyone have tips for mingling an animal that's been in the house for a while with a new one?
