Max's Veterinary Costs

My 1.5 year old orange tabby, Max, has unexpectedly took a turn for the worst. He stopped eating, stopped drinking, drastically lost weight in a short amount of time, and has become really lethargic. We took him to Blue Pearl Animal Hospital where a series of tests and X-rays were done and they found that he was anemic, had a fever of 105 (at 106 cats' organs start getting damaged), but they couldn't find the cause. FeLV/FIV/HW all came up negative. He was discharged after given fluids, antibiotics, and we were handed a $822.53 bill.  The next morning I took him to a non-emergency vet for a follow up and more treatment. They could not find the cause, gave him fluids, and told us to continue monitoring his temperature and continue giving him his antibiotics. We were given a $80 bill. A week later, after he seemed to be getting better fever-wise, he had another follow-up appointment. His anemia had gotten much worse. He was very dehydrated. They told me that if his anemia didn't get better, he would need a blood transfusion. They still do not know the cause, so they performed an addition complete blood cell count (CBC) and X-rays. They sent us home with an appetite pill and subcutaneous fluids (IV) to give to him at home. This bill was $477.93. When the CBC came back the next day (today) they told us that his red blood cell count is 25% (and it's actually lower than that due to his dehydration) which means a blood transfusion may be necessary. Red blood cells help carry oxygen throughout the body. Because of his lack of RBC's, he is breathing at a faster rate than normal, he has zero energy and can barely move, his toepads and his gums are completely white instead of pink. He also may have an abcess on his lung, and he might have pneumonia. This is what might be the cause, but they don't know for a fact. I picked up 2 antibiotics, an additional appetite pill, and probiotics. This bill was $63.57. If the antibiotics don't work, further testing will be needed (an ultrasound and a BLA). With the blood transfusion (which I'm pretty positive is going to happen when I'm off work tomorrow) we were quoted at $2,500. Blue Pearl Animal Hospital - $826.33 WellHaven Vet Follow-Up - $80 WellHaven Vet Follow-Up Exams - $477.93 WellHaven Vet Meds - $63.57 Blue Pearl Animal Hospital (Quote for Blood Transfusion, BLA, & Ultrasound) $2,000-$2,500 With all of these bills, I will be spending $3,947.83 so far. This is for the 3 vet visits, the medicine, and the future blood transfusion. I've spent over $1,447.83 so far. He has an additional follow-up vet visit at our primary office on Monday at 4:40pm, which will be more money. This has been 100% out of pocket. Any and all donations would be appreciated. I know times are tough and a lot of my friends are out of work. Please help however you can. Thanks, we love you. ♡ -Natalie & Maxwell Dokken
