Restoring Health & Happiness to Senior Cats Since 1992

About Us

After a decade of working exclusively with cats in his own private feline practice Dr.Wackerbarth became aware of a curative, non-invasive, treatment for feline hyperthyroidism that was not readily available in the Pacific Northwest.
