That`s great news flowerfairy, really pleased to hear your new micelings are faring well.
You will always see these respiratory bouts now and then and when I read your post, I couldn`t just ignore it. I used Baytril a lot when I kept my mice who were all rescues or little mice advertised on sites like Gumtree etc...and when I was going to my vet and being prescribed Baytril numerous times and seeing no results from it, myself and my vet had a lightbulb moment and decided the dosing wasn`t being given often enough and for safety reasons, didn`t want to overdose. But the one dose a day was not proving effective at all.
Yes, they do have a whiff of pepe le pew!
But they are worth it. Some good tips there also from Engel. x
