Urgent Help for Amanda's Cat Otis' Surgery

Hi there my name is Steph and I am starting this for my best friend who just came home from vacation today to find her male cat Otis to have a urinary obstruction. She has already been to the ER vet and is going to another vet that has offered to do the surgery at a slightly lower cost. I have been in this stressful situation myself and seen it many many times when working in the veterinary field, it makes you feel helpless. We all have a point in our lives that we just need a little help and right now Otis and Amanda could use some help. Like so many of us her cats are her kids and she desperately wants to help him. Amanda has his brother at home also. I know things are tight for so many people right now, me included but I am asking for anyone who feels inclined to please help if you are able to. Please also share this. Thank you
