You can really tell the love and concern they have for Shima when her paw got trapped. I've never seen camera-san so worried before. Please feel free to skip any footage next time you feel uncomfortable with uploading. Glad to see Shima is fine, thankfully.
Awww glad to see Shima is fine. Maybe you should try letting them going through step by step, first letting the pet hole open fully until they're comfortable walking through and slowly integrate the close door.
