I paid $150 for my last visit. This was for 2 cats, complete examination, distemper shots, rabies shots. This is a really nice cat clinic too in Alexandria, VA
EDIT: I just saw that you're in Alexandria!
A really good vet that I've found is Kingstowne Cat Clinic
http://www.kingstownecatclinic.com/
The vets are very very nice and thorough and they always spend time with us and answer any and every question we have. This might sound silly but I've dealt with stupid vets in the past where they get mad whenever we had any questions for them.
