25 years ago there was no internet. For me, at least. 25 years ago, I had several cats. So did my girlfriend at that time. We often spent a lot of time at each others apartments, so we brought our cats along. IIRC we left the visiting cat in their cage for 1/2 an hour, there was some hissing, then we let them out and all was fine. Maybe a hiss or swipe or two, but everyone got along just swimmingly. I now have two 3 year old cats (sisters). My sister in law who lives upstairs just got a new kitty. About 8 months old. Sister in Law is on vacation, so we thought it would be best to just bring this new guy down to make friends with our 2 girls. Ain't happening. Going on 2 days now where nobody has touched a morsel of food, and they each stationed themselves to a corner of our apartment. One of mine is hiding in the bedroom, the other on top of a kitty condo in the living room, and the poor new guy is hiding in the bathtub. If they venture away from their spots they do so as if Godzilla is lurking about, and if they see any other fur, they start hissing and growling. They're all hissing and growling at me, too, but I just knock them upside the head and they stop. I'm kidding . Anyway... We did everything according to the internet instructions my wife read before tossing them together. What's your experience with mixing the kitties up so that they all play nicely. Wondering if I should just bring this new guy back upstairs to the lonely empty space he'll probably feel a lot more comfortable in.
