Ah hell yah.
We have a couple and they whistle at me from the other room whenever they hear a knife hit a cutting board. Fun to take their cage top out and let them eat a section of lawn. Now all I need is about 100 of them so that I don't have to mow the lawn anymore.
Pimpin' Pigs!
Mine whistle whenever they hear a bag crinkle, they know carrots or celery is usually inside 😂
