Caretaker left cat without access to water for days and died as a result

I went out of town for 5 days and a co worker offered to check on my 4 cats while I was away. I came home to find they had no food or water and their litter box hadn't been cleaned in days. My oldest girl was in really bad shape, she couldn't move her back legs at all. I thought she just fell down the stairs and broke her back. Took her to the ICU and the doctor ran a lot of tests. The doctor explained to me that nothing was broken. She was extremely dehydrated, likely due to not having access to water in days. This caused a previously unknown/undiagnosed diabetic episode which set her into shock. She suffered for two days in the ICU before the doctor told me she was only getting worse and a decision had to me made. There was nothing they could do and she was terrified and suffering. I stayed by her side as they euthanized her. That was about 3 days ago. My heart is in pieces. There is no signed document of my friend agreeing to watch my cats. But I have text messages of when I tried to check in on them, then 42 messages in the morning and another 4 hours worth of messages from this friend trying to blame me for not reminding her and not telling her about an undiagnosed condition and even blaming me for trusting her.I know I'm angry and grieving. But because of what this person did my cat suffered for days until I had to let her go.Is there anything I can do? via /r/legaladvice https://ift.tt/2AKvimO
