I made Nesta a new bed in anticipation of his arrival. I used the finest velvet and even made a Burberry welting. The inside is stuffed with memory foam. I thought he'd cherish it. Wrong. He opened the bed, pulled out the inside, and ate the foam. In addition, Mr. Nesta has already outgrown the 40 inch bed! 7 months- 74 lbs. and 27 inches.
