Positives - I love the practice, doctors, staff & care my animal receives.
Negative - Cost is too high. When I compare with friends in the area who are also happy with their vets, about 1/2 say I'm paying too much, and about 1/2 say that's about what they pay. That tells me that they are not way out of line, but there are less expensive alternatives that still provide good service.
If I weren't so busy with other aspects of my life, I'd take the time to shop around.
