Wow, good on you!! I'm so pleased your furry crew approves and that they appreciate it, and your efforts !I can play music, nature sounds or a heartbeat through it too! We are just learning about all our options but the cats love it! It comes with a portable monitor and I can take it with me all over the property. It even has night vision. Yes! I sure could have used this three years ago! Very happy to have it now though.
