My dog, Buddy, hates one of my cats. At least that’s the way I’ve always interpreted their relationship. Tiger is at the head of the pet hierarchy, and Buddy, at the bottom.

I’ve seen evidence of this as the dog remained trapped on the patio, despite a wide-open door, simply because the cat was glaring at him. I’ve heard Buddy whine, confined to the bathroom because Tiger was blocking the exit. I’ve watched Buddy jump off his comfy spot on the couch, just because Tiger walked into the room.

Imagine my surprise then, when I found them laying side by side on my bed. What was this? Could it be the end of the world – when the lion lays down with the lamb? Possible, but unlikely. Could they have somehow not noticed each other? I watched for a few minutes, and they watched me back. It was clear they were aware of each other. Had they called a truce? That would be awesome. I get tired of their incessant meowing and barking arguments as they steal each other’s food, and chase each other around the house.

Peace seemed possible for the next half hour. They lay side by side without a meow or growl. I thought they looked cute and snapped a few photos. They didn’t move. I marveled at their adorable behavior and considered giving them each a treat. Then doubt crept in. What if they were sick? Or what if they were plotting something behind my back, communicating through animal pheromones?
