If it's the baby I sent you yesterday~ He will be fine if you wait until next Tuesday to feed. I know your worried that his card lets you know his last feed was the 20th~ but it will not hurt him at all to go two or even three or four weeks if you had too. He is a big, fat, healthy baby. I know he looks little to you~ but for a guy his age he is definatly a fat baby! I intentionally did not feed him last weekend because I knew he was being shipped Monday. (And I was busy~ sometimes everyone runs a bit late of a "regular feed"~ it won't hurt them at all).
If I were you I would go ahead and give him a couple days to mellow out (without being handled) and then feed him this Saturday (or Sunday~ or Monday~ whichever day fits best into YOUR schedule). Then give him two days to digest~ THEN start handling him regularly (except for the two days after every meal). He is a baby so he will probably act stressed with handling~ but if your gentle and just hold onto him while he will mellow out in short order.
