Well I guess I should mention that they've been dealing with each other for about 5 years now, and it's mostly just alot of show ! You know, arched neck & back, nasty insults and chasing each other up & down the hall. Ladies, ladies. The fur never REALLY flies. After all this time, there's really no danger of real aggression, so don't worry! As a matter of fact, they usually end up sleeping fairly close to one another on the bed at night...But not too close!
Now the peeing has become more of an "insult" than a marking of territory....They pee quite a bit on each other's favorite toys & resting areas! The bulk of the pee is on the walls in the main hallway where they both have to walk...Oh yeah, so do we!
We're working on that "separation solution", but we're just not sure how, right now!
