? pancreas treatment

Is there a holistic pancreas support treatment that anyone uses? i think I read about some enzymes pills somewhere?? My kitty fell out of remission and took to vet and cannot find anything wrong, so thinking I might start some holistic treatment.
also my kitties tryglycerides are high and vet says its her food. anyone recommend a food that is would lower tryglyceides?
I drew the lantus insulin into the syringe and removed it from the insulin bottle. THEN I noticed I did not draw out enough insulin. The syringe did not touch anything, can I put it back into tshe insulin and withdraw more insulin?
