Cat advice needed (long)

[indysteel]

I think we've made a bit of progress this weekend. Most if our upstairs is off limits to the cats. So we took them both into our master bedroom for some supervised visits in what we hoped was neutral territory. Izzy is still fixated on her, but she mostly just watched her from a distance. The few times she started to chase, Matilda stopped her in her tracks with a few hisses. So, while we don't have detente, we don't have war either. This morning, Matilda chased a ball around the room and Izzy more or less left her alone. Our thought is to continue this process upstairs until there's virtually no real aggression before trying downstairs, where Izzy is more territorial, again. I imagine this is going to take a while.
