Cicero: finally was able to drain all the sebum from the cyst on his back. The hard, pea sized lump on his back is now gone, and their is just a small hole which I will be keeping clean and watching for any sign of infection. His noisy breathing is completely gone, however, I am a bit concerned about his breathing in general. You can see his sides move more than my other rats when he breathes. No discharge from eyes or nose, lungs sound clear from what I can tell.
Nymeria: discovered quite a bit of crusty dried blood in her left ear. Discovered a small laceration on the tragus (not sure if that is what it is called in a rat, but that's about the same location as that of a human). Cleaned the site with saline wash.
Scheduled Aniston's mammary tumor removal for May 3rd.
