Your cat may not be as old as you think
At least not in human years. Conventional wisdom used to be that cats age seven human years for every feline year. The limitations of this calculation become particularly obvious on the high and low ends of the age spectrum. With advances in veterinary care, some cats now life well into their teens and even into their twenties, which, using the old paradigm, would make a 15-year-old cat 105 years old, a 20-year-old cat 140 years! On the low end of the age spectrum, a 9-month-old kitten would be the equivalent of a 5-year-old child. If you’ve ever had a 9-month-old kitten, you know that they act much more like a teenager than a young child.
The American Association of Feline Practitioners (AAFP) recognizes that there is a better way to classify feline life stages. Individual cats and individual body systems age at different rates, and while any type of age grouping is inevitably arbitrary, they felt that the new age designations take physical and behavioral changes that occur at different ages into account (for example, congenital defects in kittens, obesity prevention in young cats). Of course, aging is a process that is influenced by many factors, including diet, preventive care, genetics, and environment.
The following chart was developed by the AAFP’s Feline Advisory Bureau, and may give you a better indication of where on the human age spectrum your cat falls:
Why is this important? Cats need different levels of health care at different ages. The AAFP recommends a minimum of annual wellness exams for cats of all ages, with more frequent exams for seniors, geriatrics and cats with known medical conditions. I recommend bi-annual exams for cats age 7 and older. Cats are masters at hiding discomfort, and annual or bi-annual exams are the best way to detect problems early. Once a cat shows symptoms, treatment may be much more extensive, not as effective, and will also cost more.
According to this chart, Allegra and Ruby are both Juniors. Allegra is almost two in feline years, and Ruby is almost a year, which makes her fall right into the middle of the teenage years in human years. Yup – I’d say that’s an accurate assessment!
