Siggy will occasionally nibble my arm the way dogs scratch themselves with their teeth— you know, front teeth close together, lips pulled out of the way, tiny, fast bites on the surface of the skin. It’s actually quite painful and leaves little raised bruises. I don’t know if he thinks he’s ridding me of fleas, or what. (We’re working on eliminating that behavior, but it is weird, for sure.)
He also likes to walk on the back of the couch, like a cat. He climbs ladders like a cat, too. Our cat, on the other hand, comes when called, like a dog, will meow back if you call his name, like a dog, and prefers the dog’s food to his own.
