they all get along REALLY well- they wrestle and play and groom each other and snuggle together to sleep- oscar and frodo, the two males, had some trouble at first, but now they're fine- they play all the time. Frodo was an only cat for a long time, and he drove me crazy- he was so clingy and bored. So we got Arwen, then Elora, and then Oscar- they're all rescues, never meant to have more than two, but that's the way things work. I definitely think cats like company, but of course that depends on the cat!
