i too am sorry for what happened.. but thankfully he made it okay.
i just wanted to say it is very important to monitor their weights. i learned the hard weigh

okay sorry.. i learned the hard way.. you don't have to weigh every day or every week, [well maybe for kits you should like once a week] but when they are older about once a month is what my vet told me. that way for sure you know what is going on.
if you really believe he is losing weight you might want to get to a vet.
