Seems we have a society in that people won't take responsibility for their own actions and want too blame others for what they do wrong. Here you tried to protect their animals in a bad situation, and they are suing you. What a loser owner.

I saw a nice Akita pup get hit by a car, called animal control – who said it would be several hours before they could get there. I took the suffering pup to a emergency DVM and had him treated. Took the pup home and called the humane society, who contacted the owner 2 days later. All the owner did was [censored] about the cost of the treatment that I asked to be reimbursed for. It was less than the offered reward for the pup. After the owner refused to pay, I owned the pup. He became a good friend for a long time.
