Help Bob get surgery

Our cat Bob is 10 years old, and we just found out she has breast cancer. The vet says she need a full mastectomy which is a complicated and expensive procedure. We adopted Bob when I was 9 years old, and I’ve practically grown up with her. I can’t imagine a world without Bob and this surgery will give her the chance to live a long and prosperous life filled with tuna and catnip. But money is really tight, and we will appreciate anyone who can help keep Bob in our lives. Thank you.
