Please don't blame yourself in any way for Bigodinho's passing. Hepatic lipidosis is one of the toughest things for a cat to overcome. Most don't make it, and those that do usually have to have a stomach tube put in, and it's very time consuming trying to reverse this condition. And please don't let that woman bully you into paying those bills. You did more than your part IMO. RIP Bigodinho.
