How to Determine Your Cat's Age by Its Teeth

Understanding the age of your cat can be crucial for their care and health management. One of the most reliable methods to estimate a cat's age is by examining its teeth. This guide will walk you through the process of determining your cat's age by its teeth, ensuring you're well-equipped to take the best care of your feline friend.

Why Teeth Matter in Aging a Cat

Cats, like humans, experience changes in their teeth as they age. By observing these changes, you can get a good estimate of their age. This method is especially useful if you’ve adopted a stray or rescued a cat with an unknown history.

Birth to 2 weeks: Kittens are born without teeth.
2 to 4 weeks: The first baby teeth, or deciduous teeth, begin to erupt.
4 to 6 weeks: The full set of baby teeth, totaling 26, is usually present.
3 to 4 months: Baby teeth start to fall out, and permanent teeth begin to appear.
6 months: Kittens have a full set of 30 permanent teeth.

Examine the Canines: These longer teeth can show signs of yellowing and tartar as the cat ages.

Observe Gum Health: Healthy, pink gums are typical in younger cats, while older cats may have red, inflamed gums.
