I had a cat and a parakeet. That cat would sit and stare at the bird and begin to reach in. I would sneak up and send the cat right into the wall. Off the cat would run. Later the cat came back and tried it again. Same thing happened. I call it the "Cat"a put effect. The cat finally figured it out to leave the parakeet alone. I could imagine the cat would think “Man I dont know about what is happening. Everytime I try to get that bird I hit the wall. Man, that bird must be telekinetic.” Later the cat would lay on the top and the parakeet would just tweet and talk to her all day. Best friends after that. And they say Cats can’t be taught things. Yes the can.
