So I've talked to both paws and the vet and they both tell me essentially the same thing - I am required to pay in full at the appointment time but I could write a check and they can hold it until a specific date. My bank account at the moment it pretty shot, and I am not comfortable in doing that. My grandmother's anniversary party is this weekend, I am considering leaving tonight and speaking to my brother who is a Paws foster parent. He may be able to get this through much cheaper and I could pay him back whenever I get the money rather than paying the whiny vets. For people who work with animals, I really don't think they hold much compassion. I'll keep everyone posted, and I appreciate the support.
