I took him to the vet today. They did some blood work, stool samples and an X-ray. Apparently he’s fighting off some kind of infection and lost something like 40% of his body weight. The x ray showed something in his ribcage that apparently caused some difficulty breathing when they were taking the pictures, and the vet says that it could be bronchitis or pneumonia or it could be a tumor/mass, in which case there isn’t a whole lot we can do for him. He said that they could send the images to a radiologist to confirm what the mysterious blob was, but he said that no matter what, we were still going to run antibiotics to help fight whatever upper respiratory thing was causing the eye/nasal discharge, and a more broad spectrum antibiotic, so I opted to give it the weekend, see if the treatment had any effect, and hopefully confirm or debunk the tumor fear from his progress or lack thereof. He also gave him subcutaneous fluids and a B12 shot and recommended I make him a probiotic from my other (healthy) bunny’s poop. I’m hoping for the very best, but I’m very anxious.
