Thanks for all the posts. Sometimes it helps just having others listen.

Marlin is definitely fine in himself, thus far! He gets such a HUGE smile on his face come meal time! Offer him a treat and oh my, he's in heaven, lol. So he hasn't changed THAT much! Starvin Marlin is still constantly hoping the Food Fairy made a delivery to his dish, which he checks regularly, just like always.

I've always had to make sure he gets one walk a day, he gets constipated with out it. Makes for some interesting times in rain, snow and cold! Even if none of the others are interested, Marlin has a walk, I've always had to be sure of that, lol.
