She passed away this morning at home. We don't have the reason of death yet, FIL thought maybe it was her heart but she didn't have problems that we know of. At least she got to go home and be with FIL and her dogs for a few weeks.
Poor FIL. MIL went this morning and he has to put down one of their 2 dogs tomorrow. She has internal bleeding, failing spleen, but is really too old for surgery that may not work anyway. He said they knew about this yesterday, I hope it didn't contribute.
Thank you all for your support through this all. Please keep FIL in your Ts&Ps over the next days, he is so lost and alone out there (4 hours from us). We plan to go up Saturday and spend the long weekend with him, helping as we can.
