I''m so sorry you have to go through this.Poor Amber too but she's so fortunate to have you to do this for her.I've payed hundreds for teeth pulling on so many cats and between those bills and so many other vet specialist bills and bloodwork on at least half my cats and Winston with his heart...I can't believe we still have a home.But in the end it will hopefully work out.
You may not be able to see because you can't afford glassess for yourself but she'll tell you how happy she is later that you spent so much on her
I hope you find that wallet
