Good question! Those pancreatic enzymes that are measured on blood tests aren't as meaningful in cats as they are in dogs, especially lipase. Sometimes an elevated amylase can be an indication of kidney disease, but an elevated lipase, especially a mild increase as with your cat, doesn't mean anything at all.
Since she has had hepatic lipidosis, I would highly recommend a high protein, low carbohydrate (grain-free) food. Most cat foods are full of some type of grain (corn, soy, wheat, rice) which are sources of carbs. Cats are obligate carnivores which means they aren't designed to process a high carb food. Even if the first ingredient on a food is meat, if the next few ingredients include a grain, this is still a high carb food.
The brands I recommend include Wellness Core, Innova Evo, Instinct, Orijen, Taste of the Wild, Indigo Moon, Weruva and Pinnacle Peak Protein. I also recommend feeding canned food (most if not exclusively) to provide enough moisture, which is also important in maintaining health.
Good luck and thanks for your question
