I took my rat to the vet today. I posted previously about him not eating much and now I know why. He was breathing rather fast, but he does not make any noise when he breathes. Appearantly, he has severe pneumonia. I cannot put him down without fighting as much as he is, so I got $300 worth of medications. The vet said he has about a 40% chance. Has anyone else had to deal with this? Are there any happy endings out there? I am close to tears and don't know what to think.
