Thanks for the advice! I've been keeping a good eye on both babies, and... Well, let's just say I've got a pair of bottomless stomachs with feet and leave it at that.

No runny eyes, though when Zelda had it, she did have a runny nose for a day or so.

Now that Mowgli's got it, other than the cough and the wimpy meow, he acts like he feels fine. I wish I could bottle up some of his energy and sell it!
