The Senior Cat

Cats are often forgotten members of the household in terms of veterinary care, since they are by nature self-reliant and hide illness and discomfort remarkably well. According to the American Association of Feline Practitioners (AAFP), a “senior” cat is defined as a cat over 11 years of age, while a “geriatric” cat is defined as being over 15 years of age. As age increases, cats are more prone to developing subtle changes in behavior that can help clue us into various common diseases in older kitties, such as arthritis, chronic kidney disease, hyperthyroidism, hypertension (high blood pressure), and small intestinal disease.

Chronic pain caused by osteoarthritis (degenerative joint disease) is the most common condition we diagnose that causes a chronic, negative impact on quality of life. Studies have shown that up to 90% of older cats will have changes consistent with osteoarthritis on x-rays, affecting many different joints in the spine and limbs. Recognition of feline pain and pain management in cats has come a very long way in the last two decades. Some cats will develop visible lameness or signs of discomfort, but often the signs are much more subtle, such as:

  • Hesitation before jumping.

  • Relocating favored perches and sleeping areas to more accessible areas.

  • If in a home with stairs, limiting themselves to one level of the home.

  • Under grooming or over grooming.

  • Not using the litterbox, especially to defecate.

  • Reclusiveness and/or changes in temperament.

Treatment of osteoarthritis is often multimodal, meaning approached from many different angles. We generally start with omega-3 and joint supplements, as well as some prescription foods to manage the disease from a nutritional angle. Weight management is also an important part of nutritional management, as obesity creates a pro-inflammatory state in the body that can worsen disease symptoms (this is true of humans and dogs, as well!). Pain management with various drug therapies are often recommended; as well as physical therapy, cold laser therapy, and acupuncture.

Osteoarthritis and common systemic diseases in cats, such as chronic kidney disease, hyperthyroidism, hypertension, and gastrointestinal disease, often have an insidious onset and a nonspecific set of symptoms (weight loss, increased or decreased appetite, vomiting and/or diarrhea, increased water consumption, and accidents outside the litter box, etc…). The nonspecificity of symptoms, and often coexistence of multiple diseases in a single cat, is why we recommend a blood pressure and comprehensive blood work and urinalysis profile anytime a senior or geriatric cat presents with any combination of these symptoms. We may also recommend diagnostic imaging such as x-rays and abdominal ultrasound to be able to further define symptoms and come to a diagnosis. Treatment of the various common systemic diseases in older cats is also multimodal, often employing a combination of supplements, diet, and drug therapies.

In the generally healthy senior or geriatric cat, the annual physical examination is a great opportunity to review the happenings of the past year with your veterinarian, and have a discussion as to the “normals” and “abnormals” of your unique kitty. We very often have findings on our examinations that are so subtle that clients have not noticed them at home, such as weight loss and painful joints. In addition to our standard annual physical examination, vaccine, and intestinal parasite prevention protocols, the AAFP additionally recommends annual baseline blood work, thyroid, urinalysis, and blood pressure in all senior cats. Having these baseline values for an individual patient is extremely helpful for comparison to their “normal” if illness arises. For some senior and all geriatric kitties, it is often recommend to have examinations, and sometimes blood work, on a biannual basis.

Amazingly, it is not uncommon for cats to live into their early 20’s with regular preventive care, pain management, and early and persistent management of chronic diseases. We absolutely love our well-lived and well-loved senior and geriatric feline patients!

Halloween - Trick or Treat?

Halloween is right around the corner, so this week we’re going to discuss… candy!  These tasty sweets can be dangerous for dogs, particularly those that contain chocolate, are sugar-free candy and those containing raisins. Although not life-threatening, ingestion of high-sugar candy can cause diarrhea by pulling water into the gastrointestinal tract and giving gut bacteria too much “food,” leading to excess growth of bacterial populations. Specific candy toxicities are discussed below:

Chocolate contains a compound called theobromine, which is related to caffeine. Dogs do not metabolize these compounds quickly, so they can experience more intense and lasting effects of these stimulants. Common signs of chocolate toxicity are anxiousness, panting, muscle twitches, rapid heart rate, and even seizures. Vomiting and diarrhea are also common and will sometimes be the only symptom in mild cases.

The weight of the dog, the amount of chocolate, and type of chocolate ingested are all factors that determine whether chocolate ingestion is toxic. As a general rule the darker the chocolate is more toxic it is (baking chocolate is far more toxic than milk chocolate), and larger amounts of any chocolate consumed by smaller dogs carries more risk of toxicity. Milk chocolate is often more concerning for the potential to cause illness and symptoms from pancreatitis, as a result of ingestion of sugar and fat, than true chocolate toxicity from theobromine.

Sugar-free candy with the sweetener xylitol is extremely dangerous to dogs. Xylitol causes large amounts of insulin release in the dog. This leads to a rapid drop in blood sugar levels which can manifest as  uncoordinated walking (ataxia), extreme lethargy and/or seizures.

Xylitol can also induce liver failure and blood clotting abnormalities. Any amount of xylitol ingested should be considered very toxic to Any size dog; if you suspect your dog has ingested this substance, you should immediately visit your veterinarian or the nearest emergency veterinary clinic  for emergency treatment, hospitalization and monitoring.

Raisins (and grapes) have the potential to cause acute kidney failure in dogs. The frustrating thing about this toxicity is that we do not know what in the grapes or raisins causes the toxicity, and there is not a widely accepted toxic dose. Raisins tend to be more concerning than grapes as they present a more “concentrated” version of the fruit. Any ingestion comes with recommendations for emergency care to induce vomiting and, preferably, 48-72 hours of IV fluids and monitoring of kidney values.

In all cases of suspected toxin ingestion, it is advised to call your veterinarian, go to an emergency veterinarian or call ASPCA Poison Control  (888) 426-4435 immediately for further direction. If it is determined a toxic dose of a candy has been ingested, seeking medical care to induce vomiting as soon as possible is the best course of action. Depending on the amount ingested, further treatments may be indicated such as: administration of activated charcoal to help absorb toxins within the gastrointestinal tract, intravenous fluids, hospitalization, and drug therapy.

We wish everyone a happy and safe Halloween — and remember to keep that candy out of reach of the pups, which means the more for you as well!
