My four eyed opossum Robin is having a bad week. Since her surgery a week ago, she has eaten nothing. She has been drinking but eating absolutely nothing. I took her back to the vet and it turns out that her surgical site is infected and smells horribly, so we came home with one oral antibiotic; a suspension of SMZ, whatever that is, to be given twice daily. I do not yet have instructions to bathe the smelly wound or anything additional like that. We were able to force feed her some puppy milk replacer before we went to the vet and we gave her some more afterwards along with the antibiotic. I also have some vanilla ensure I am going to try and we are trying to locate something called Nutripet or Nutrigel which is a gel form nutrient and energy supplement that you can force into their mouth and it wont spill out.
