Vet care for Millie, Buddy and Fluffy

Millie, Buddy AND Fluffy all need vet care.
 Millie was recently diagnosed with congestive heart failure of the right side of her heart. She's on meds and needs to see a cardiologist. I made an appointment for June 30th (praying that the money for it will come in somehow). Fluffy was born with a heart condition and is overdue for her workup by the cardiologist. I've notice signs that it's time for her to get evaluated, (blueish color to her tongue when she's active and a pale gum shade). The estimate that I got from Blue Pearl cardiologist is $847 per pet. That doesn't include any medicines that may need to be prescribed.
 Buddy was diagnosed with collapsed trachea syndrome and needs to get X-rays and bloodwork from his regular vet. The estimate for buddy is $265. without the cost of any medicines that may need to be prescribed 
 Why am I asking for help? During Covid19, I became furloughed from my job for 42 days. I was deemed "eneligible" by Florida state unemployment, because I had been out on Worker's Comp early last year from an accident, in which I needed surgery. I'm currently fighting that decision. A week ago, I had to send Sugar (another family fur baby) over the rainbow bridge. She was suffering too much to keep her here. It was a difficult decision and has made me realize the importance of the other three pups health. I can't allow these three angels to suffer and am asking for assistance for their sake. I thank everyone who takes the time to give and share, it means so much to us!
