Mookie's Car Accident Expenses

Just this morning my sister's best furry friend Mookie got hit by a car on our street. Unfortunately, the car sped off and drove away. We had to rush Mookie to the vet because he was not able to walk and he was bleeding. We found out he has a large bruising in his lungs causing a lack of oxygen. Without the oxygen chamber and further tests and possibly surgeries, he will not make it.  Mookie is staying in the oxygen chamber overnight where he can be monitored.  We are so grateful for your help.
