Liver Disease In Cats: Know The Signs

by | Dec 9, 2016 | Cat Behavior & Care | 5 comments

Has your cat ever snubbed the food bowl? Neither of mine has, although Karma is a bit picky–but I’m very watchful because loss of appetite could mean cat liver disease.

CAT FACTS, THE SERIES only from Amy’s Newsletter

I’m sharing this information from my CAT LIVER DISEASE entry from Cat Facts, The Series 12 (L): The Pet Parent’s A-to-Z Home Care Encyclopedia which includes these topics:

Laser Technology, Lice, Litter, Litter Box, Liver Disease, Lower Urinary Tract Disease (LUTD), and Lungworms.

I’ve broken the massive CAT FACTS book into catnip-size alpha-chapter sections. Folks can choose which ones they most need. Each chapter will release every week or so, but ONLY for subscribers on my Amy’s Newsletter Of course, you can still get the entire CAT FACTS book either in Kindle or 540+ pages of print.

WHAT IS CAT LIVER DISEASE?

Liver disease is any condition which impairs that organ’s normal function. The liver is the body’s metabolic headquarters. It serves a dual role both as a kind of factory, and as a filter.

The liver processes sugars and fats, stores vitamins and minerals, and makes necessary proteins and enzymes. The liver also manufactures hormones and important blood-clotting substances, as well as the bile that’s necessary for absorption of fats. The processed material is either stored or delivered throughout the body as needed by the blood.

Blood is also filtered as it passes through the liver. Substances like drugs that are carried by the blood are metabolized, or altered, into other forms. Bacteria, toxins, even viruses are shifted out of the blood system by the liver. Liver disease is serious and often life-threatening to the cat, and is estimated to affect about three to five percent of sick cats seen by veterinarians.

SIGNS OF CAT LIVER DISEASE

Liver disease mimics other illnesses, and often the sick cat has problems in other body systems at the same time with symptoms that overlap. Cats that have liver disease can also suffer from diseases of their intestinal tract and pancreas, a triaditis where all three are inflamed at once. The signs of various kinds of liver diseases are remarkably similar, and typically include:

  • loss of appetite
  • vomiting
  • diarrhea
  • weight loss
  • lethargy
  • jaundice (yellow tinge to skin)

Because signs are so vague and resemble other feline health problems, the cat owner may not realize the cat’s in trouble until the disease is quite advanced.

DIAGNOSING CAT LIVER DISEASE

A profile of the blood is the first step toward diagnosis. Liver enzymes may be elevated for a number of reasons, though, and elevated enzyme values does not automatically mean the cat has liver disease. Blood tests, imaging techniques and symptoms can point to liver disease.

A definitive diagnosis can only be made examining tissue beneath the microscope. An ultrasound-guided needle allows cells to be collected through the abdominal wall, often without invasive surgery. This biopsy generally is done by anesthetizing the cat. Cells may be collected using a fine needle inserted into the liver through the abdominal wall, or the procedure may require surgery.

Treatment depends on the cause of the problem and how early it’s caught. Once the liver scars from the inflammation, the damage is hard to reverse. Inflammation of the liver—the various hepatitis diseases—is treated with drugs to suppress the inflammation. Veterinarians try to select drugs that rely primarily on the kidneys to process.

Overweight cats that stop eating are at higher risk for fatty liver disease.

KINDS OF CAT LIVER DISEASE

Fatty liver disease (hepatic lipidosis) is the most common. Overweight cats are at highest risk for this condition, and the definitive sign is when an obese cat suddenly stops eating. For reasons not completely understood, fat is moved into the liver and becomes trapped, resulting in compromised function. A feeding tube may be placed to allow the cat to be fed a soft diet, either while in the hospital or after going home. It may take weeks of tube feeding before the cat’s appetite returns to normal.

Hepatitis (inflammation of the liver) usually is the result of exposure to a toxin like chemical insecticides, or drugs like aspirin or Tylenol. Treatment consists primarily of supportive care, and removal of the poison. In certain toxicity cases, early intervention allows the liver to recover with little or no damage to the organ. Prednisone isn’t a cure but reduces inflammation in some kinds of liver diseases and cats improve without many side effects.

Cholangiohepatitis is an inflammatory condition of the bile tract that interferes with the excretion of bile, and is considered the second most common feline liver disease. Cure is rare; therapy is designed to control the disease. When caused by bacteria, long term antibacterial therapy is prescribed. Conditions that result from over-reaction of the immune system require immune suppressing drugs.

HOLISTIC LIVER TREATMENTS

Holistic veterinarians recommend a number of herbs and supplements to help cleanse and support the liver. Dandelion helps remove toxins, and milk thistle has been shown to help the liver generate new cells and protect it from toxins. Nutritional supplements such as raw beets contain natural chemicals that also work very well to support the liver.

Some holistic vets recommend creating a raw liver formula by combining raw egg yolk, raw sheep or beef liver, a teaspoon of honey, two tablespoons of plain yogurt and a cup of water in a blender. The nutraceutical SAMe (S-Adenosylmethionine) increases antioxidant levels in liver cells to protect them from toxins and death and often is used to treat liver ailments.

Fortunately, the liver has quite a bit of built-in redundancy, and only a small portion of the organ needs to function to maintain the cat’s health. After some insults, it’s fully capable of regenerating to its original size.

Do you have a fat cat, or ever struggled to keep your cat eating? I hope you’ll never be challenged with cat liver disease! Please share your experiences, though, to help other readers.

    Well, 2016 is just continuing to be awesome at gut-punching me with unpleasant coincidence.

    It’s the 1-year anniversary of when Anubis died… of liver failure.

    In his case, of course, it was basically just age that did it, so there was no reversing it. :\ Or, the vet said theoretically we COULD but at his age the cure would have been worse than the disease and wouldn’t be worth it.

    • Amy Shojai

      Oh Karyl, I’m so very sorry. {{{{hugs}}}} Older cats do, indeed, face multiple organ failure/challenges and I know you balanced Anubis’s quality of life with all options.

    Very interesting post, I hope I never need the information though..

  3. Lois Gleim

    Great information, we are taking our cat to get him checked out for his eye, he has to go to a kitty eye doctor and we can’t get him in till August.

    We had a complete blood work up to see why is causing his eye trouble, they don’t seem to know.
    When the test came back everything was okay except his liver levels were high and he should have to see another vet to do and ultra sound. He is 13 years old and weighs 13 lbs. we are working on having him lose weight.
    I pray he don’t have anything really bad. He does not fall in all of list above showing signs, other than weight.

Chiropractic Care & Back Problems: Home Treatment Tips

Chiropractic care…do you use it? In the past I’ve had back issues and got relief after visiting my chiropractor. Chiropractic care works as well in pets as in people, too. In fact, many people with performance dogs regularly schedule chiropractic treatments for their canine athletes..

Cat chiropractic care may not happen as often. After all, felines practice their own form of yoga to stay limber. They’re also much lighter weight than many dogs, and perhaps that puts less strain on their bodies. Read on for some home care techniques that can help your pets.

Love Thrillers? Reminder about Emily Kimelman & Sydney Rye Series

👀 I spy a steal…I’m head-down in the plotting/writing of my next SEPTEMBER & SHADOW THRILLER #7! Lots of “schtuff” keeps sidetracking me from finishing DARE OR DIE, but hope to get the next story into your hands this spring. Meanwhile, here’s a reminder I’ve lined up some more great books for your reading pleasure. If you love crime and thriller stories with dogs (hey, you’re reading mine, right?) check out Emily Kimelman’s gritty Sydney Rye Mysteries, too. Oh my doG, tail-waging grrrreat fun.

The tagline of the series gets me every time: Sydney Rye and her dog exact justice with a vengeance. The dog doesn’t die, but the bad guys do.

I get that question a lot about my September & Shadow thriller series, too. So I borrowed (stole?!) the line from Emily and include it whenever folks ask. I also loved what she says about the dog “aging out” in the book…that it’s FICTION so the dog can live forever! (Heck, I just may steal that, too…don’t hate me, Emily!). Read on for a great deal on her books!

How to Leash Train Cats

Why would you want to leash train cats and confine kitties from stalking and pouncing? Isn’t that mean? Actually, it’s not cruel, but without proper introduction, it can be a wee bit scary. In my Complete Kitten Care book, I call this LIBERATION TRAINING. Teaching your new cat to walk on a leash is a safety issue, but also means they get to venture beyond the confines of your house and into the yard and beyond.

This week during a cat consult, a pet parent asked about training her cat to walk on a leash. It’s always a good time to revisit the notion. An adult cat won’t automatically understand the concept, though, so this blog not only explains the benefits of leash training to YOU, it also helps you purr-suade your cats to get a new leash on life. Sorry, couldn’t resist.

Dog Choking & Cat Choking: First Aid & Pet Heimlich Help

Have your pets ever choked on something they chew? Shadow-Pup loves to chew up inedible objects, no matter how much we supervise. Learn how to administer the pet Heimlich to save a life!

When Karma-Kat came to live with us, that put lots of cat toys within Magical-Dawg’s reach. Seren had never been too keen on such things and she was already nine years old when Magic came as a puppy. He loved to swipe Seren’s “sparkle-balls” and ended up with sparkly poop. Once Karma’s toys added to the kitty quotient, the big ol’ dog had a field day seeing how many cat toys he could stuff into his jaws.

Bravo played with rocks. And the new puppy Shadow loves to chew sticks. He’s already got one caught in the roof of his mouth. That’s the perfect opportunity for choking, and a need for the pet Heimlich. I hope that we’ll never need it, though. In case you do, read on!

Do Readers Care Why I Write

Do readers care why writers write? One time at a writer conference, that question was asked and an overwhelming response was, “I write because I HAVE to write, it’s  compulsion, I must write…” And an agent on the panel responded, “They have medication for that now.”

Ba-da-boom. *rimshot*

My audience doesn’t read. Well, unless you count dogs and cats chewing up or (ahem) “being creative” on paper. And of course, cats “read” by sitting on top of the words and absorbing the text through their furry nether regions.

Yvonne DiVita tagged me years ago in the “Why I Write” blog hop. I know Yvonne through the terrific BlogPaws.com organization she co-founded, but today you’ll find Yvonne at NurturingBigIdeas. As I updated several out-of-date blog posts, I found this one as true today as when first written more than a decade ago. I talk more about my writer’s journey at my website, but here’s the crib notes. *s*

Why Dogs Bark & How to Stop A Dog from Barking

Do you know how to stop dog barking? “Will you please, for the love of doG, stop barking!” When Shadow-Pup joined our family, he and Bravo-Dawg egged each other on. Now that he’s the only dog, he and the cat tease each other and prompt bark-fest and meow-athons.

We love our dogs, but when noisy dogs get revved up, dog barking can drive us nuts. Shadow has a “demand attention” barking problem that shatters glass. He also loves barking at squirrels and tells on Karma-Kat when the cat gets on a counter, and at us when we can’t read his mind.

So what’s the answer–how to stop a dog from barking? The key to stop barking includes understanding why dogs bark.

Scaredy Cat? Teaching Shrinking Violet Shy Cats

Do you have a scaredy cat? Working with fearful and scared cats can be a challenge. Does Sheba hiss at strangers? Does Tom dive under the bed when the doorbell rings? Do your kitties attack other pets (or humans)? What can you do to stop bad behavior if even a mild correction sends the cat into fearful meltdown? Alexa posted her Ask Amy question to my Facebook page, and the answer is in today’s video.

Helping Shy & Scaredy Cats

We often feel that our fur-kids must have been abused and feel bad to make THEM feel bad. But they still need to know limits. One of my favorite ways to train is using positive rewards. Instead of waiting for kitty to scratch the wrong object and then interrupting the behavior–why not REWARD her when she scratches the RIGHT object?

Using kitty clicker training can also build confidence in shy cats by teaching them what happens is in their paws. Here are more tips for dealing with scared cats.

Cat Neatness Freaks: How & Why Cats Groom

Does your cat groom nonstop? We cherish the cat’s fastidious nature but did you ever wonder why cats groom? Neatnik behavior goes beyond looking good. Did you know in this hot weather, cats also groom to stay cool and prevent heatstroke? 

How and why cats groom impacts physical, emotional, and social health. My Karma-Kat even tries to groom his best friend, Bravo-Dawg. The instinct starts during kittenhood and lasts a lifetime. Of course, some cats get dingy when cats don’t groom, and there are reasons for that as well.

Grooming is a barometer of kitty health. Cats that feel bad often stop grooming, or lick and pull fur out due to stress or pain. Consider an unthrifty appearance or “barbering” themselves bald a kitty cry for vet care. Cats often need help in the grooming department—especially longhair beauties. Here are 5 common reasons why cats groom.

Please Fence Me In: Creating Good Neighbors & Keeping Dogs Safe

Do you have a dog fence? Magical-Dawg used to take off after “critters” every so often, racing around the 13-acre spread (or beyond). We eventually trained him to stay with us, even when off-leash. It would have devastated me if Magic disappeared. He was microchipped, but folks would need to catch him first.

Bravo was a very different dog. He was so good off-leash during most morning rambles and didn’t want to go too far away from us. He’d chase and play with his “big-ball” in the field, and baptize every tree and grass tussock. And once he lost his leg, he couldn’t get out the back fenced area even if he’d wanted to.

 Shadow-Pup, though, takes after Magical-Dawg. He’s so small, not even the fenced back area keeps him contained. He also likes to dig, so we needed to address possible escapes. Refer to this post for more help with digging dogs. Until recently, we had to keep him on a leash anytime we went outside, and that’s no fun for him–or for us. A fence is a dog’s best friend!

Dog Training & Cat Training: How to Clicker Train Pets

People often ask when to start puppy training, and training a kitten or cat training is no different. Pets can learn at any age. January is “Train Your Dog Month” so it’s a great time to revisit clicker training. Clicker training pets offers a great way to teach pets to learn, think, and please you. Pets—and people—will repeat behaviors that reward them and naturally avoid behaviors that offer no benefit. Owners don’t have to be master dog trainers to use this technique, and dogs and cats learn quickly how to behave. You can even trick train cats! Read on to learn how.
