New to the Too world n in love. But, i question whether they have eaten carpet fibers. They love to pull,, really pull and are thrilled to win the tug of war. I do not ,, of course encourage this but it's been done. They don't seem disturbed but have a new stretching of their neck n sticking out of their tongue. They are eating fine, and play well. They recieved a vet check in the begining and were fine. Is this typical behavior or should I seek attention?
