It is very important for your pet's health to visit a veterinarian at least once a year for a wellness exam and vaccinations. Routine exams ensure your pet's continued health and vaccinations prevent illnesses transmitted by other animals. Some illnesses, like feline leukemia, can be easily prevented but will never go away once your pet has contracted it. It is also greatly advised that you spay or neuter your pet. This will not only reduce the amount of animals in need of homes but it also prevents many health issues further down the road.
