Dante the Best Boy Needs Help

Normally we would never ask for help, especially during this Covid-19 pandemic, where so many are struggling. But, circumstances leave us no alternative as the reason is one of the Best Boy Cats ever. Dante is the sweetest cat you'll ever meet, but more than that he has a huge piece of our hearts. He is only six years old, and before this, was never outwardly sick a day in his life. 
However, late last week we began noticing that our Best Boy, the blue-grey kitty with big green old soul eyes, was walking more slowly, hiding, and refusing food and water. After taking him to the veterinarian, we were devastated to learn that not only did Dante have a bladder infection, but that he also had feline leukemia, a virus that had lain dormant in him, waiting to attack when he was fighting off the infection.
Dante has spent a few nights at the animal hospital, and he came home today when our finances ran out. In the hospital he was on IV valium to stimulate his appetite, antibiotics, and fluids to keep his fever down. He has deteriorated rapidly since coming home. We know he belongs back at the hospital to give him the best chance of kicking this infection and living anything resembling a normal lifespan. He's only six years old.. we need more time with our buddy!
We are asking for anything you can give, ASAP, so we can take him back to the hospital tomorrow morning, where he can get the fluids and appetite stimulants he needs to have a fighting chance. It will buy him 2-3 more days of intensive treatment we simply cannot afford, having reached financial rock bottom getting him this far.  If none of that works, and he's just too tired, we will use the money to give him 'the good, gentle sleep', though it breaks our hearts to type that. He's SUCH a good kitty.. he doesn't deserve to suffer. We need our boy, and his sister Marshmallow needs her brother.

Please, anything will help, and if you wouldn't mind sharing Dante's story far and wide, we would be unendingly grateful.

Thank you,
Frank, Jen, Marshy, and Dante
