Urgent Help for Tank's Surgery Costs

Hi, I come to you to ask for help with Tank's vet bills. Tank woke up this past Friday unable to walk and in severe pain. His stomach was so tight I thought it was constipation; I wish that was all it was, but I took him to the emergency vet today, Saturday, and was told that he had paralysis in his hind legs due to a slipped disk in his spine. To fix this required surgery, which he had, but now we are looking at the vet bills that had to be paid before they could even touch him. Because of this, we applied for credit cards that were approved, but now we need the money to pay them off, hopefully before 6 months, so we don't end up paying a very high APR.
