Sick cat... My own vet couldn't fit us in any time in the next four hours, and their walk-in branch 20 minutes away said there might be a two-hour wait after I arrived, but the Animal Care Center worked us in even earlier than the appointment I scheduled with them. (Also, with them I didn't have to wait on hold for 15 minutes!)
The staff and vet were kind, calm, pragmatic people. The vet didn't push expensive tests, explaining his reasoning well and discussing the next steps he recommended if my kitten didn't feel better by a given time.
I plan to switch to this clinic.
