Sick Sugar Glider Needs Treatment

My 8 year old sugar glider has been diagnosed with an abscess. Under these circumstances it could leave to potential death. His brother had been seeing exotic and dental specialists at Cornell University. His symptoms started with lower jaw abscesses on and off for almost 2 years. We spent a lot of time pulling teeth, taking xrays, running ct scans, cultures, etc. Unfortunately Meeko did not make it and I had to make the decision to put him down in September. Needless to say, I'm beginning to love this nightmare again. I found his lump on Christmas. Cornell would like to run a full body MRI to check for tumors, bad teeth, or any other abnormalities. I also had surgery 3 weeks ago and with Christmas 2 days ago, money is very tight and any help for his care would be greatly and forever appreciated not only by myself, but for his brother and girlfriend who live with and love him.
