I weighed Sam and Dean this morning. Sammy weighs 2 lbs 1 ounce and Dean is 2 lbs 3 ounces. I think that's a good weight based on their age and size, but I will know more on the 24th when they see the vet. Dean is slightly bigger in size than Sammy. Just about 2 ounces worth. For comparison, Scruffy is noticeably smaller than both of them, but not by much and he weighs 1 lb 13.5 ounces, which the vet says is good for him.
