Elderly Cats Special Considerations

30th July 2018

Cats are living much longer now than was the case 20 years ago, thanks to better nutrition, veterinary and home care. In recent years, feline ages and life-stages have been redefined, cats are considered to be elderly once they reach 11 years with senior cats defined as those aged between 11-14 years and super-senior cats 15 years and upwards. When caring for older cats it sometimes helps to appreciate their age in human terms.

The formula for calculating the equivalent age is fairly simple:

the first two years of a cats life equate to 24 human years and every year thereafter is equivalent to 4 human years. For example, a 16-year-old cat would be equivalent to an 80-year-old human.

  • Kitten the young cat is growing rapidly and is usually not quite sexually mature
  • the cat reaches full size and learns about life and how to survive it
  • Prime the cat is mature physically and behaviourally, and is still usually healthy and active, looking sleek and shiny and making the best of life

After that, cats tend to develop more slowly, Barrack said, aging about four or five human years every 12 months.

How Old Is My Cat A Vets Perspective

Because every animal matures at a different rate, even veterinarians have trouble knowing for certain how many years, months and days a cat has been on the planet. They can, however, make a very educated guess.

When Im giving someone an estimate on their cats age, I tend to start by looking at the teeth, Barrack said. Teeth can be strong indicators of a cats potential age, especially in younger animals. A kittens baby teeth will usually start to come in when they around three weeks old, with all 26 being present by the time they are around six weeks old. Ages between three to six months can be determined by the rate at which the baby teeth are falling out and their permanent replacements are coming in.

If veterinarians see a full set of adult teeth, they usually assume the cat is at least six months old, and if those teeth are clean and sharp, the cat is likely younger than two. After that, however, things can get murky. Beyond age two it becomes a lot harder to tell the cats age by its teeth, Mears said.

Beyond the physical exam, lab work on older kitties can help veterinarians pinpoint a patients age. Kidney issues may show up around age ten, and hyperthyroid indicators a year or two later, however Mears said that he has seen these in cats as young as six or as old as 22.
