mine is about as bad as they come and was because of a trio. the trio worked the first time they had babies, the second time, they snatched both of each other's babies from each other, inverted each other's pouches and both had infections. Unfortunately Destiny had the worst. we were only able to save one baby out of the four from this
puts a shadow over my head about trios now so i have all pairs by self choice... but here is a pic.sorry so graphic and not sure this is what your looking for....
she did heal up fine from this with an antibiotic injection. sorry if you were looking for something somewhat different
