So honestly this is a good app, but the singing option sounded like something I heard in a book where if a Guinea pig sounds like a bird singing, it means they are in danger, so I don’t think it’s a Guinea pig singing, I mean, they probably can sing, but I’m not sure about the noise in the app because it’s wrong. Also, I don’t like the option “get back or I’ll break your legs!” Well first of all, a Guinea pig can’t actually break your legs and I found it a bit offensive to be honest (sorry!) but I still think it’s a good app! My guineas were so confused!
