My poor cat needed to see a vet ASAP for a fat lip... actually, a rodent ulcer. He had been here many times and was actually super comfortable. I'm amazed. The vet took her time and was very friendly. She told me to buy him vitamins and that they may be cheaper online. She also explained to me all options for future treatment in the case that antibiotics didn't clear his lip problem. She recommended many household changes and pointed potential causes for the lip. I made a couple of changes, got the antibiotic and he is all clear! Not only that but his new vitamin is working and he loves it! I purchased on amazon as recommended.
