Karen I am SO extremely sorry. My mother had a VERY bad experience with a local Vet here ( We only have 3 to choose from ) and filed a complaint with the state board of vets...While my mother's sitituation is different (She had a very old Daschund with cancer. Opted for Euthanization rather than "Experimental Surgery"....Vet decided to do surgery then "foster" the dog out... Sent my mother a BILL for Euthanasia AND Cremation!!! Even a Sympathy card!..... Twiggy only lasted one more year and when she did cross it was very traumatic...My mother unfortunately did not sue but had a case...) You (Your Mom)can try to file a complaint with your state board. I think you are in Cali, right?

I wish you luck and I am so sorry you and your Mom had to go through this.... I've been there, unfortunately I was told things like this happen far more often than most people know.

Take Care,
