10 Hours - They are bright pink and only weigh 6–8 grams (not much more than a nickel). Their eyes and ear canals are sealed. The light spot on their left side is a tummy full of milk. |
| 36 Hours - The babies are showing pigment, eye color, and have clearly put on weight. |  |
 |
5 Days - Their coats are beginning to develop and you can usually tell what color they will be. Their ears are up but the ear canals are still sealed. |
| 11 Days - Their coats are well developed and their ear canals are beginning to open. They are becoming more mobile. |  |
 |
14 Days (2 Weeks) - This is the day their eyes open and they begin to explore their cage. |
| 2½ Weeks - Their eyes and ear canals have been open for a few days. Their coats have become soft and fuzzy, and they are eating, walking, and beginning to play. |  |
 |
4 Weeks - They are eating everything in sight and growing at a phenomenal rate. Mom is beginning to wean them and they spend their waking hours playing very hard. |
| 6 Weeks - The babies are well developed, completely weaned, and ready to go to their permanent homes to be wonderful pets. Males and females MUST be separated at this age. |  |
