I'm sorry to hear that she's still so sick. Hopefully the medicine will kick in soon and start making her feel better. In the past I've done the bathroom steam thing and also the vaporizer. I never really noticed much difference though because my cats became stressed out in the bathroom and wouldn't go near the vaporizer. If she ends up getting worse during the long weekend then you can always call an ER vet clinic for advice. I'll send some prayers and positive thoughts her way. Please take care keep us updated about her.
