sick kingsnake???

[hightower]

is Ernie sick? please can you offer your opinions.

he's still moving about ok and still loves coming out and being handled, however, he seems more scared of his food than trying to eat it, and this morning i found a larger than normal amount of poo in the tank, and it was quite runny. could it be that he had just crapped before i woke up hence the freshness or is there something not quite right???
