Merlin's Hospital tests and care

Merlin had a sudden need to go to the Emergency room Hospital.  He was breathing heavy, low blood pressure, dehydration, unwilling to eat and drink. They put him on fluids and oxygen, and over night a few of his symptoms improved. Although they noticed him coughing up blood and need to perform more tests. They are unsure of the cause of why he's going through this- but he is.  As many of you know he is my companion animal. my best friend and emotional support in so many ways. Me and merlin would be so grateful for your financial help right now so we can figure out whats going on and hopefully recover from this.
