OMG one of my boys named Sammy does that too whenever he hears a bag. I have 15 pigs and they'll all start screaming everytime they hear a bag crinkle, and Sammy will do everything to outsqueal them XD
I just wanted to let you know that I have subscribed to your channel finally! I love all of the guinea pigs ❤! I used to have a guinea pig that I named Black Jack he was half black and half reddish orange 🧡🖤. I got him as a baby but he unfortunately has passed away back in 2010 and I miss him so much
