Caring for senior cats

CARING FOR THE SENIOR CAT

There are now more pet cats than dogs in North America. Improved nutrition, prevention of infectious disease and advances in veterinary medical care has resulted in pets living longer and healthier lives. Over the last ten years there has been a 15% increase in cats over 10 years of age and the proportion of the feline population aged 15 years or older has increased from 5% to 14%. It’s a great time to be a cat!

Why should we treat old cats differently to young cats?

1. With advancing age body functions change.

As cats age, all of their body systems are affected:

  • Reduction in exercise may result in reduced muscle tone, which may further reduce the cat’s ability to jump, climb or exercise. This may also lead to a stiffening of the joints and arthritis
  • When coupled with a reduced metabolic rate (common in older individuals), lack of exercise can result in a fall in energy requirements of up to 40%. If a cat maintains a good appetite, its daily food intake must be reduced to prevent excessive weight gain.
  • Inappetance (lack of desire to eat) may develop in some senior cats since the senses of smell and taste become dull with age and periodontal (dental) disease is common.
  • Gut function and the ability of the intestines to absorb nutrients are reduced in older animals.
  • Thirst is also decreased, causing an increased risk of dehydration, especially when combined with concurrent renal insufficiency (kidney disease which is common in older cats).
  • Most specific nutrient requirements are not yet determined for senior cats. However, it is often assumed that older cats have some degree of subclinical (underlying) disease, particularly of the kidneys and liver, hence a diet with moderate protein restriction is usually recommended.

2. With advancing age, any medication must be given carefully.

Changes in physiology not only affect food absorption, they also affect the way many drugs are metabolized. Liver and kidney disease occur commonly in older cats. When coupled with mild dehydration, these can result in reduced drug clearance rates and marked elevations in drug concentrations circulating within the blood. When treating geriatric patients, the dose and dosing intervals of some drugs may need to be altered.

Does my senior cat still need to have regular booster vaccinations?

Although little is known about the feline immune system, it is generally assumed that with age immune function may deteriorate. This may in turn result in a reduced ability to fight infection or screen for neoplastic (cancer) cells. Regular booster vaccinations are generally recommended and prompt treatment of disease is essential. Our veterinarians will determine the appropriate vaccination program for your cat based on its physical condition and lifestyle.

What diseases do senior cats commonly get?

The major diseases seen in older cats are hormonal disorders (such as hyperthyroidism and diabetes mellitus), kidney disease, neoplasia (cancer), infections (e.g. feline immunodeficiency virus [FIV]), periodontal disease and arthritis.

It is important to remember that while young cats usually have only one disorder at a time, this is often not so in older patients, where diagnosis and treatment may be complicated by the concurrence of multiple interacting disease processes.

While it is true to say that “old age is not a disease”, it does merit special attention. This is important so that if your cat develops disease, we can recognize and treat it as early as possible, thereby maintaining its quality of life for as long as possible.

What can I do to make my senior cat as happy as possible?

Most cats age gracefully and require few changes to their general regimen. Since older cats do not generally respond well to change, it is important that any changes are introduced slowly.

Elderly cats should have easy access to a warm bed, situated where the cat can sleep safely without fear of disturbance.

It is strongly recommended that you feed your older cat a senior diet. They should always have easy access to fresh drinking water.

As cats’ age, some will experience a reduced ability to control urination and defecation. To reduce the risk of “accidents”, it may be necessary to allow access to multiple litter boxes.

Senior cats should have regular health checks with their veterinarian every six months.

During your cats Annual Physical Exam your Veterinarian may recommend the following:

  • Blood screen
  • Blood pressure check
  • Urinalysis
