Persistent cold and cough

[Nanno]

Hmm, we don't have thick yellow-green at all. It's clear and runny or white and thickish, but not a trace of green or yellow (except after it's dry or when there's alfalfa bits stuck in it). Everyone but Petunia and her kids seem to have shrugged this off in a couple of days, no problem (although it's supposed to get very cold tonight and tomorrow, so we'll see if anyone else gets worse again). I'm sure my vet would be very good about selling me a bottle of just about whatever I said I need on hand, but it's going to be next week before I'm able to go fetch it.
