I accidentally taught my cat to come when called by letting her have a treat when I was giving one to the dogs. She is now better than them at it.
you know how when you go to a concert or show of some sort and the person on stage is like “HOW’S EVERYONE DOING TONIGHT?!?!?!?!” and the audience cheers back? why? you’re not answering the question, you’re just yelling. imagine if we did that in daily conversation. “hey jeff, how are ya?” and jeff just starts screaming and clapping in your face
