I had a litter Feb 2004 which consisted of 5 babies. The mother was 4.5 and the father was 5. I keep in touch with the new parents and the largest of the babies was a boy and is 6 pounds and the smallest in the litter is a boy and is only 19 ounces. They will be a year old in a couple of weeks. You can see this litter from newborn to current on my webpage

The little tiny one Dobby, is on the main page. When they went to the vet at 8 weeks old, the Dr said they looked like they were from separate litters. Take a look.
