Our pride now sits at four. That wasn't intended, but it happened. Two are ARL rescues (city cats) and two are off the farm. The farm cats are very much hiders, but just as playful and affectionate when relaxed. Our 15-year-old needs meds, and that's when they become more like dogs. When their day-to-day health depends on you events require planning ahead.
Of note, when free roaming neighborhood cats visit, which is rare, the ARL cats will scream and fight each other. (They never leave the house, except rarely supervised on our 2nd story deck.) The farm cats will cower under the bed.
