If you have owned an animal, or if you know anyone who has, chances are you have heard of the terms spay and neuter.

The Importance Of Cat Wellness Exams

Very tiny calico kitten held in two hands

It is very important to have a veterinarian examine your cat at least once a year. Cats age significantly faster than humans and therefore it is imperative for cat owners to stay on top of wellness exams in order to catch any potential health problems before they begin. Most cat illnesses are much easier and less expensive to treat and cure when caught in the early stages before they progress or develop complications. Therefore, regular cat wellness exams are the cornerstone of preventive veterinary medicine.
