Thank You for the compliment on my babies.
Momo is like a Yorkie roomba...he'll lick the kitchen floor, eat my hair (& I have long hair), eat lint from the dryer.
I think he has pica. It all comes out the other end, but he will make these sounds often. He'll even eat rubber bands & I've had to pull out his tootsie roll w/a long piece of some plant leaf stem.
We're very careful not to drop anything & vaccume & clean the floors often.
I've even taken him to the vet & had x-rays done when he first started doing this. There were no signs of a collapsed trachea bc that's what I thought it was.
