You are not alone. I had to laugh because I too am not bothered by the chewing of my pets, nor any sounds they make for that matter. I wonder why that is? I also don't like white noise. Having the TV on as background noise makes me crazy. Fans whirring away seem to have a suffocating effect on me.
Thanks for making me feel like I am not alone my fellow Misophoniac. :)
Haha Im so glad to find other Misophoniacs! Maybe we love our pets that much so its ok hearing them do that nasty noises :P Oh so you have more sounds annoying you thats cool! lol And yes, you are not alone! Lets conquer the world! :P
