Hi everyone, I just adopted two super handsome kitties from a shelter, but they both have the feline herpes virus. The virus causes their eyes to water and "goop" quite often. I try to stay on top of it, but sometimes, especially over night, the goop hardens and becomes a lot more difficult to remove. So far I've just been using tissue and water to clean their faces but the hardened goop is tricky to get off. Any suggestions?
