Smokey's Vet Bills

I am out of work again because my last contract ended on 08/23. Smokey has two white lumps in her ear. I took her to a vet a few months back who told me to bring her back if they grew or changed. There was blood around one so I brought her back. They gave her an antibiotic and did blood and urine tests. I'm waiting for the results. The doctor told me if the lumps didn't go down I'd have to get them biopsied as they could be tumors. Smokey is 16 years old. I'm trying to put some funds together to pay for all of this. I used a credit card to pay for the original visit but can't afford to keep creating debt while unemployed. I'm hoping some kind people will help me out. Thank you.
