Those poor, poor darlings! I pray they get better real soon, they are soooooooo adorable! Especially Newton and the little Meezer! I wish I could give them a huge cuddle. We once had a litter of kittens struck by something like Cat flu and it was awful! I know how it feels. We lost one, the one I wanted to keep. Fortunately for the rest, whatever it was was soon killed by antibiotics. Good luck with treating the little ones, getting a steamer sounds like a great idea!
