In the Portland, Oregon area - Dove Lewis gets all of the media attention - but I take my kitties to the Emergency Veternary Clinic in Tualatin.
(funny how often they like to wait to get sick until the regular vet is closed. )

This place is fabulous - once saved my in-laws kitty cat when she was very sick with pancreatitis. Address is: 19314 SW Mohave Ct Tualatin, OR 97062
