Hi, we are new owners of two young female guinea pigs and I’ve noticed that one of them today has a cut ear. This only happened today as they are handled daily but I have noticed one of her ears previously looks ‘different’ to the other. I’ve attached photos - can anyone advise? I’ve bathed with salt water as I’ve seen this in previous posts but am concerned about the overall redness / possible lack of fur compared to the other one. Any help would be appreciated or am I worrying about nothing? Thanks in advance.
