Update on my sick rabbit. She was stable for a while, but in the last couple of days she got bad. She was barely eating, drinking, and breathing heavy. She also felt very bony (list 1.5 pounds) and wasn't as lively. I took her back to the vet and her fever was back - this time a 105.4 degree fever, which means she could have died at any time. I tried so many meds and her fever kept returning, which the vet said means that there is something serious going on. She was also moving and shaking her paws in a strange manner that almost resembled a neurological issue (this was just within the last few days, she has been sick for a month). Unfortunately, we made the decision to put her asleep. The vet said she most likely had a cancer we couldn't detect. RIP Spirit.
