Now I've read of something similar a while ago ...

There have been cases of snakes making the noise you described and the owners incorrectly presumed it was a RI when in some cases it was small bits of substrate in the nostrils or mouth/ throat .... that's all I can remember ... What kind of substrate are you using ?? Does it sound feasible in this case maybe ??

I know some snakes go tunnelling through and under the substrate especially when they're trying to rub the old skin off and that would explain how the substrate gets in there ..

It's just an idea .
