Help Cali Marie get back to the vets

Hello my name is Melissa and this is my baby Cali. I recently have taken her to the vet in which it had cost me most of my income for this month. She was diagnosed with pneumonia and that's what they treated her for but received a call from the vet today stating it is not pneumonia and they would like another visit to have blood work done and more tests! So I am asking for a little more help if possible since my funds were depleted this month from her first visit. The funds I had already received were a huge help and I appreciate the kindness from you all, but still need a little more help. Also please say a little prayer for my baby..thank you!
