Hi, I noticed my cat had a swollen lower lip yesterday. I took her to the vet today and he just said it was allergies and gave her a shot and told a lot of stuffs could do this. I would love to hear your experiences. Her wet food bowl is stainless steel and dry food bowl is a slow feeder from EveryYay brand, It feels like BPA free plastic but she has been eating from it for the last couple of months. Her diet has been Hills I/d care and Indoor health mix. I am not sure if it's the food. She has always had water eyes since she got Upper Respiratory Infection when she was a kitten.
