Save Sprocket

My best friend, Sprocket, has recently had a bunch of medical tests and procedures to determine what's causing his Pleural Effusion (fluid around and between in lungs). He started having difficulty breathing last week and has been in and out of the vet, ER, and vet specialist offices ever since. Sprocket has lung lobe torsion surgery tomorrow to hopefully help him. Sprocket is a sweet boy who has been with me for six years. He is happy and quirky. He has so much left ahead to live for. Any donations to his medical expenses and care would be appreciated. Please help me save my best friend.
