Clients frequently tell me that they think their cat or dogs like each other but they aren’t sure. They sometimes point out that their pets sleep together, but does that mean they’re best friends? It could but it doesn’t necessarily. They could just be sharing beds because it’s comfortable or convenient. True “friends,” actively seek eachother and hang out, play together, and perform affiliative gestures such as mutual grooming.

Here’s a photo of Jonesy and his bratty younger, but bigger sister, Lucy. Jonesy pretty much just tolerates her. Sometimes he puts up with her pestering, and other times he exercises his Sailor’s mouth. When she’s in the more comfortable bed he sometimes joins her because that’s the most comfortable spot.

Here’s Jonesy with Homer (tricolor JRT) and a visiting JRT. Homer would actively seek Jonesy out and lie next to him. That would sometimes make Jonesy grumble under his breath. Homer did indeed look up to Jonesy. But, as usual, Jonesy could care less about Homer.

Tell me about your pets who sometimes share a bed. Are they best friends or just convenient buddies?
