How Old Is Your Dog in Human Years?
There is a popular belief that one year of a dog's life equals seven human years. This is false because there are many factors influencing a dog's age. For example, smaller dogs live longer (on average) than larger dogs. Veterinarians now have a more accurate way to determine a dog's age:

The aging of cats is also complicated and converting a cat's age to human years is an educated guess at best.

Are you uncertain about the type of veterinary care your cat needs based on his or her age? The American Association of Feline Practitioners and the American Animal Hospital Association partnered to produce guidelines that promote age appropriate care for cats. The guidelines address health, nutrition, behavior, environment, vaccinations and parasite control issues for each of the feline life stages.
1. Kittens: Up to six months of age
2. Juniors: Seven months to 2 years
3: Adults: 3 to 6 years
4. Mature: 7 to 10 years
5. Seniors: 11 to 14 years
6. Geriatric: 15 years and older
As with dogs, many factors influence a cat's aging process. There is no specific definition of a senior or geriatric cat. In general, cats seven to ten years of age are mature, equivalent to middle-aged humans in their forties or fifties. Cats over 15 years of age are considered geriatric by most veterinarians. These classifications are arbitrary. A cat is not suddenly a senior on his eleventh birthday.

Know Your Cat's Health
Determining your cat's health status can be a challenge because cats are masters at masking their pain and suffering.
Many of the most common diseases display few, if any, clinical signs during the early stages.
Notify your veterinarian if you detect any of the following in your cat:
-
Changes in chewing, eating and drinking habits.
-
Drastic weight gain or loss (more than one pound a month.)
-
Withdraws from social interaction and avoids touching.
-
Changes in activity level, including sleeping more or hyperactivity.
-
Increased vocalization.
-
Increased urination, struggles to urinate (an emergency situation), or bypassing the litter box.
-
Changes in bowel habits: constipation (straining to go), diarrhea (soft or liquid stool), visible blood.
-
Grooms less or grooms certain areas excessively.
A sudden change in your cat's diet can result in diarrhea. Go slowly when transitioning to a different food.
When it comes to your cat's health, timing is everything. Start by paying close attention to your cat's attitudes and actions. With advances in veterinary medicine, many diseases are treated or managed easily if they are caught early. By scheduling regular veterinarian exams for your pet, and identifying subtle changes in your cat's behavior and eating habits, you can become a better pet parent to your cat.
Feline Health Care Tip:
Weigh your cat monthly. Two extra pounds on an adult cat is like a ten to twenty pound weight gain on a person. As with humans, obesity in cats leads to multiple health problems including diabetes, heart disease, joint degeneration and arthritis.
Caution: Rapid weight loss in an obese cat can lead to liver failure. Any weight reduction must be done slowly. Please consult your veterinarian before placing your pet on a diet.
