Hello, I am Nicole, proud owner of 5 guinea pigs. One of my female piggies has developed a large cyst on her back. I've come through some hard times, and it is killing me that I can't bring her to the hospital. The cyst is huge, bigger than a quarter, and it has opened up into a very large wound. Anything helps to get closer to the goal so I can bring her to the emergency room ASAP. Thank you all.
