Help cali get surgery

Our cat named Cali was at the vet today (5/28/16) and we found out that she has been diagnosed with pyometra, which is an infection in the uterus. She was given antibiotics and a IV fluid bag. There is a chance that she will need an operation to get her uterus removed, this is an expensive procedure, and we need some assistance with doing this, so please help use in reaching this goal, and help our family stay together. She is only 7 years old and still has a full life ahead of her, I don't want to see anything happen to her
