Brett,
Was there any signs of fat along the intestinal tract?

Active lions should receive only enough food to cause a noticeable bulge in the abdomen.
I would recommend feedings of three times a week.
Non-active or lions in small confines can be reduced to feeding once a week with occasional feedings of twice a week.

When I ran an Aquatic Rescue, lions were the number one saltwater inheritance.
Many would lay lethargic and not eat for weeks (some nearly a month) before thinning and becoming active.
