Please Help Ninja the Cat!

On Wednesday 7/26, I came home from an 8am work meeting (*grog*) to find my cat, Ninja, gushing blood from his mouth. I immediately turned around & went straight back to work, hoping it was something simple like he cut his tongue or had a bad tooth. One of my favorite MEAC doctors did a thorough exam & noted a bruise on his hard palate & bleeding around one tooth, but couldn't tell where the blood was coming from or why. Ninja was hospitalized & given yunnan baiyao (medicinal herb) to help control the bleeding. Unfortunately, it was ineffective & he continued to bleed during the night, so the next morning I took Ninja to the Hope Center. There, the ER doctor suspected a tooth issue, but later confirmed the bleeding was coming from the bruise on the roof of Ninja's mouth. I was referred to the Center for Veterinary Dentistry & Oral Surgery. It was there that Ninja had 2 teeth pulled, plus surgery to put a flap off skin over the bruise/abrasion in his mouth. Unfortunately, at this point, he was so anemic, he had to go straight back to MEAC for monitoring his PCV. When I first took him to MEAC, it was 25% (normal is usually high 20s, mid 30s). At this point it had dropped to 18. Unfortunately, by Friday afternoon, it had dropped to 11. Friday night/Saturday morning, Ninja received a blood transfusion. I'm happy to say it was successful & his PCV has increased to 22, but it's been a long (& expensive) few days! Any & all help would be greatly appreciated. Thank you!!!
