I have a small cat who has been able to open doors at my house since she was a kitten. I tried blocking access, she would climb over obstructions. I even used sticky tape to try and hold the screen door shut, but she would lay on her side and pull it away anyway. In this cute video, the cat is helping get someone in, not out. That would be a big change at my place. Check it out.

This cat goes to great lengths to help this small group of puppies. Maybe she is training the puppies to be rescue dogs, and this is their first lesson of observation!
