Kind of expensive?
Many of the reviews point out that these guys are "kind of expensive". My opinion is that they are outrageously expensive. They charge 3 to 4 times more than PetMeds for medicine.
After spending almost $2,000 for diagnosis and treatments, the cat did not get any better.
Their response was bring him in for blood work (at $200 per pop), again with no results.
In summary, I wouldn't use these guys again under any circumstance.
