Okay, so on one of my little kitties (7 months old) I just noticed late last night that her lower lip was slightly swollen, so I was keeping an eye on it and today it's seems to get progressively worse. It's like her lower gum is slightly protruding and you can see it when you just look at her. I'm wondering if it's because she could have got in a fight and got injured, or if it's possible allergies, I'm not sure. I've had cats my entire life and have never encountered this. So wondering what your thoughts are? D:
