I'm so sorry to hear that this whole thing was so traumatic for poor Socks and your mother.

I would absolutely complain to the Better Business Bureau. Click Here to go to the BBB web site. Your complaint might have more of an impact with the state board of Vets, like Katie suggests, but I would still make a complaint with the BBB. The one time I made a complaint with them, they contacted the other party and played intermdiary between us. At the very least they might be able to get your Mom's money back, and they will, at the very least, know that there was a complaint made against them, which might just prompt them to be a little more compassionate in the future.

Good luck with everything, but most importantly, tell your mother to not feel guilty about anything she did or didn't do. The guilt part is a normal part of the grieving process and she needs to know that whatever she did, she did for Socks, and she did it because she loved him.

Hugs to both of you at such a stressful time.
