Hey there, I have an approximately 8 year old feral but friendly female kitty I am trying to help. Her nose and eyes during summer gets these really bad blisters, but during winter she seems fine. Otherwise she is very energetic and happy.
Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Midnight. And thank you also for providing a picture, that really helps. I'm concerned she has a serious skin condition going on, that looks awful in the picture. I'm worried with all her time out in the sun, she could have developed squamous cell carcinoma. It could be she has been sunburned every summer causing the blisters and now may have cancer. She really needs to see a vet for it. I would see if you can catch her and get her into a vet asap. I hope this helps!
