Why might my healthy, adult cat need lab work done?

Mainly for baseline lab values. We like to track the numbers over time to see if they do get sick in the future where that started and see where those changes happen and how long it took for those changes to happen. We might also get lab work with kittens to prepare for anesthesia, if needed, for a dental cleaning or some other procedure.

Adult cats can hide things. So, that would be one reason to do a well check—to detect problems early and serve as a baseline.
