Well, not in love exactly, but these two pals clearly enjoy snuggling and grooming. They pat, nibble, lick, gently nip. The musical sound track keeps us from knowing if the cat’s purring or the dog sighing, but their bodies certainly are.
I once had a dog who was not fond of cats. Then two cats came to live with us. They followed him around adoringly. He learned to tolerate them but never to really like them. At the same time, we had another dog who followed them around with slavish devotion, while they ignored him completely.
Come to think of it, sounds like some relationships.
