This is my girl mercury in the worst state she's been in yet. For the past two weeks, her neck has been occasionally swelling, more times than not and with different intensities. This picture shows the worst that it's been. I am assuming it is edema and i am doing everything i can to keep it down but nothing seems to help, it really just comes on goes on it's own time. In the past day iv'e noticed swelling in her eyes as well. this picture also shows the worst her eyes have been. They swell for a few minutes and then it disappears, and repeats. I am so worried. If anyone has an idea as to what could be causing these to happen, please contact me. I purchased her very young from petco almost two months ago, and shes guessed to be around 3 months of age. I will be reaching out to a vet tomorrow to try and schedule an exam.
