Okay, so my cats have started working as a team to ambush me.
I have a small end table with a lamp by the back door, and the bigger car Achilles loves to jump up there and meow for treats. We call it his "begging spot." Sometimes he gets them and sometimes he doesn't, but when he does, I give treats to both the cats.
I've noticed the past couple of days that the little black cat Luna, who is normally very quiet and only meows for food or treats, has started to come into where I am (generally my office) and meow at me. Then she'll walk a short distance, turn and meow again. If I get up to follow her, she leads me to where Achilles is sitting in his begging spot, at which point they both meow at me. It's so cute that I feel compelled to give them treats for their cooperation.
Though some might be more inclined to call it "conspiracy."
