After being overcharged at another vet, I found Cat Clinic of Seattle. Their prices were lower, they were willing to work with me on things--doing a few tests, not a whole battery of 'em, and were really good with my cranky old cat.
They showed concern, even when my cat came in for a "psyc" visit (she screams like a rooster at sun up and sun down--no joke). While Cat Clinic isn't dirt cheap, generally, if you say up front "Look, here's my limitations..." they work with you.
Dr. Johnson is esp. good with freaked out cats, calling them "Baby...ohhh....little friend...every things going to be OK...." and just cooos at them. I appreciate that they send my prescriptions to be compounded (my cat HATES pills), and took the time to do a quick re-teach on giving fluids (I was freaked out--poking my cat with needles was NOT OK with me).
Be sure to bring your cat in a carrying case of some sort, as they're required in the waiting room.
