I made a couple of posts about my rat who was supposedly with pneumonia. I've been treating him with the whole package (antibiotics, antiinflammatories, probiotics, etc) but as soon as I dropped the meds he got worse. I just done a second x-ray and found out it was cancer all along. The vet said there's nothing new can do, only delay the inevitable. Is there anything I can do? ( I atteched the todays x-ray)
