Thank you all for your suggestions. Yes, I was feeding the kids from plastic bowls. I bought new stainless steel dishes this weekend, and I am keeping my fingers crossed. One problem is that Norman and Isabelle (Norman's sister) are terrified of the new dishes. How they hate change!! I know they will get over their fears, but I feel so sorry for them. Dinner time was one of their big excitements of the day!

I'm also cleaning Norman's chin each day with cotton soaked in a light saline solution (this was a tip from my cat care book). No new outbreaks to report. Let's hope this clears up "the problem."
