Mirrajay,
After you are well rested, let us know how the trip went for you. I hope that it was good for you, and your four legged child.
I also called the USDA vet here in Richmond, Va, and I was also quoted about $107.00 for the first animal, and then about $6.00 each for the other two additional animals. The cost of my other two animals was a very nice surprize for me as I thought that each one would be about $100.00 each.
The pets is the most frustrating process of getting over to the UK. Our visas were easy compared to the animals.
Best of luck to you !!!
Keep us posted how everything went for you when they released your animal to you in the UK. I am anxious to hear of personal experiences.
