So since he wouldn't eat last night I weighed Odin today just so I could keep track and make sure he isn't loosing to much. Well last week he was 59g and he has dropped to about 55g this week. At 16" he is pretty thin. If he was an adult I wouldn't be concerned about a 5g loss but given his size and he hasn't eaten in 3 weeks should I be thinking about a vet visit or should I wait another week like ya'll suggested?
