When Dylan was about two, we thought, hey, he's grown we can keep him in the kitchen with his sister, ( baby gate across the doorway ) and they will be fine. Well........ We had a large square kitchen table and when we got home it was round!!!!!!!!!!!! He had chewed all the corners off!!!, then he had chewed the window sill off!!!!! We took him to the vet, long story short he was fine, but we had to crate him after that until he was about five. Bless his heart, that was many many years ago, I wish he was still with us :(
