Yup, that sound's like my STINKY BOYS

They are silent but deadly.LOL sometimes Phoenix makes alittle sound and it lingures to so sometimes i have to check under his tail and make sure he did'nt have an acciedent LOL

Aspen just does it and then looks around like Did anybody know that was me? Or what the heck was that.

Hopefuly soon i'll have a stink free house
