Several of you suggested "steaming" KC to help with her lingering URI.
We bought a vaporizer and the usual helpers were waiting to set it up.
Smokey, Faith Boomerang and Sol were attentive to every detail.

Faith-Boo took a special interest in the filtered water inside the unit.

She checked and re-checked...

...sampled and re-sampled...

...and finally agreed the unit was ready to use.
KC napped, wrapped in Sol's paws, right beside the vaporizer.
Thanks for the suggestions, she is breathing much easier now.
