Our cat recently had an acute episode of pancreatitis. It took numerous vet visits before we could even figure out what was going on. A lot of blood work, IV therapy, and imaging later, we finally had the answer. Healthy Paws covered everything, no questions asked. They are extremely easy to work with.
In general, they process claims extremely quickly -- within a few days. This time around, it took a bit longer, but due to the size of the claims (over $3,000), I can't blame them.
