Tumor removal surgery for Momo

A few months ago I discovered a small lump on my pet rat Momo, which I observed for awhile until I started suspecting it was a malignant mammary growth. Recently I discovered a second one has grown, which scared me to death..

I took her to the vet recently who affirmed my suspicions, but thankfully the X rays showed that the tumor hadn't metastasized. The vet recommended swift surgery to remove both tumors.

Only problem is, I can't afford the surgery. I tried alternative options like a monthly payment plan from a firm that works with my vet, but since I'm currently unemployed I'm not eligable for it. I really don't want to lose Momo and this surgery could potentially help her live a long, healthy life as well as avoid putting me through the pain of euthanizing her when the tumors eventually do metastasize and spread.

I hate asking for money as a rule.. in fact, I've tried selling some of my most valuable belongings on Kijiji to avoid doing so, but nobody seems to want them and I'm stuck with no other options, and it's only a matter of time till it's too late. The only reason I'm doing this is because I love Momo so much that I'll try almost anything to help her, even if I have to resort to crowd funding, which is my absolute last resort. I just want to have her with me for as long as I possibly can.
