My Pooh is around 7 1/2, he's relatively healthy.  He is on Prednesolone
for insulanoma.  He eats Totally Ferret for seniors with a good appetite.
I'm not sure though if he is in pain when he does this.  Every now and
then he will start to foam (not always) at the mouth and start what
looks like a chewing action but nothing in the mouth.  Sometimes when
he is sleeping in my lap he will all of a sudden wake up and start this
chomping at the mouth.  After a few minutes he stops.  More often he will
just chomp/chew with no foam.
 
Does anyone have any idea.  I kind of freaks me out.
 
Thanks,
Steph & Pooh
