Purrley,
I understand the nervous feeling you will probably have. Everytime something is done to one of my pets, I am a basket case until I see them again. Since she is so tiny and delicate is there any way you can save up the extra $40.00 and have it done by your regular vet? I always use the term with my husband "I'm sorry, but I don't want to be penny wise and dollar foolish!" There are times when you get what you pay for.

This has to be your call and comfort level! When the time gets closer and you still don't have the money, contact me and perhaps I can help you out.
