Save My Cat

This is my baby Bandit. He is 8 years old and got sick suddenly about 2 weeks ago. We have taken him to our vet and an animal hospital. We thought it was just a cold but the xray showed something in his lungs. He is having trouble breathing and won't eat or drink. We have been giving him an IV. He needs an ultrasound and possibly surgery. I don't want to lose him. He means so much to us but I don't make enough to cover these services. We are in desperate need of help to save our baby. Please!
