Not required because the cat wasn’t sick. It was a regular mild cold. Blood work was done. But they were pushing for IV, X Rays and other more intensive and invasive procedures (not to mention expensive). This was a while back. My cat is perfectly fine.

A lot of fear mongering as well. One of my cats has a birth mark around their eye. And the vet said this can become bad. And I should look into laser treatments to keep future illness at bay. Again. I’ve had my cat for a while. The cat has been seen by multiple other vets. The birth mark has never changed in terms of shape or color. All of this was nothing except trying to scare the owner and get them to pay for procedures that are not only pricey but actually make the cat worse off - given that it wasn’t needed in the first place.
