My kitty lives on the porch. He has a kitty door and comes in and out of the porch whenever he pleases, but never in the house. We spend a lot of time on the porch, I plop Keira down on the rug and she "plays" with him..he lays next to her, she touches him, tugs at his fur. He's been in contact with her since birth. Ive noticed in the last week or so that her face breaks out in a rash within 2 hours of us being on the porch, but it resolves overnight. Could she be allergic?
