How to Teach a Cat to Open a Door
Contrary to popular belief, cats can be trained. You can certainly train your cat to do things like coming when called, sitting, or targeting an object. Training it to open a door may be a little bit more difficult, but with some patience, you'll likely succeed. Start by clicker-training your cat, then work on training it to use a target stick. Use the target stick to teach it to open the door.
