I'm new to multiple cats. For the longest time, I thought cats did not get along with each other. That they weren't social animals, and only tolerated...I dunno, it doesn't make sense now. Because I have two littermates now, and I watch them doing their thing all the time. Their adorable 'competitive grooming'--they don't always take turns, so they both groom the other's face at the same time--and their slightly creepy 'moving the same way at the same time'. Today, though, I encountered something that I can't make sense of. El 'announced' or 'greeted' me [still working out her language--it's a process], then, a bit later, Morti came into the room. El meowed like she did when she saw me. Cats don't meow to each other, though, right? My question, I guess, is: people with more than one cat--what just happened? Did El greet Morti, or did El announce Morti's presence to the rest of us? Do your cats ever meow to each other? Is this another thing I 'know' that's wrong?
