I definitely know about the trials and tribulations of getting cats together. My husband's cat definitely was stubborn about getting to know my cat. After about 6 months (you wouldn't know it by looking at them today! )they could tolerate each other and now(couple of years later) they're just the best of friends. Good thing my Marius was so laid back and tolerant of Scooter's set of lungs and attitude those 6 months!!
