I have never heard or had anyone come out in the waiting room to sell a list of test, that is ridiculous, especially when they didn't even know what the list was all about.

Before even checking MK out, they start telling you that she is going to need this and going to need that. Balony.
Then they CAN'T tell you WHY she will need these tests.
I don't blame you for ranting Lori, it sounds so unprofessional to me. I can't comment on the Glaucoma test as I have never heard of this either.
Maybe there are certain tests for an outdoor cat, I really don't know, since my cats have always been indoor.
I'm glad to hear that she had a clean bill of health though.

Hopefully someone will be able to give you some answers in regards to all of this.
