Hi Angela
Wendy asked me to pop in about the whole pancreatic enzyme discussion as I have some experience here,
Exocrine pancreatic insufficiency (EPI) is a nasty buggar. Cats with EPI don't have the enzymes needed to break down essential nutrients for absorption. Cats most prone to get EPI are those who have had chronic pancreatitis. Often foul smelling, fatty stools are a hallmark sign of EPI but other conditions can also result in that kind of stool. Other symptoms would be a constantly hungry kitty (but this would also apply to an acro kitty), weight loss, generally poor coat (looks greasy), and body condition. A cat with untreated EPI looks like its starving and, basically is. This is a condition that
absolutely must be treated.
I'm wary of treating for EPI without testing for it because the treatment is pancreatic enzymes which (a) always require a prescription from your vet (b) are very pricey and (c) can burn the cat's digestive tissues if not administered correctly.
Texas A&M GI lab runs the test. You can have just the serum fTLI done but I don't know the cost. However, this is one of those conditions that I absolutely, personally, would not treat without a diagnosis. If anyone just offers to send you some pancreatic enzymes without you having a dx, I would encourage you to not accept.
Digestive enzymes are quite different and I, again personally, believe every cat no matter their health should be taking a good digestive enzyme meant for animals like
Animal Essentials.
The Petalive pancreatic booster is, as Bobbie said, just an herbal pancreatic support and may or may not have any therapeutic benefit.
I hope that helps.
