Shadow was recently diagnosed with Patent ductus arteriosus or PDA. The TL;DR of this is that a vein that is used to bypass the lungs while in the womb should collapse once he is born however Shadow's is still open. This is causing his heart to struggle as it is now pumping blood incorrectly.
The surgery to correct this is expensive as it is heart surgery. We'd do anything for him but unfortunately we cannot afford the surgery.
Any help would be greatly appreciated by both us and our little furbaby.
