repeated effective behaviors and abandoned ineffective ones.
Explanation:
Based on the information provided within the question it can be said that the cat in this scenario seems to have started repeating effective behaviors and abandoned ineffective ones. This can be seen, since the cat stopped making the same choices that did not help it get out of the box, and instead started repeating the choices that allowed it to escape. Which is why it was able to keep escaping faster and faster with every attempt.
