Hmm, that sounds very cheap if they are using general anesthesia, placing an IV and doing pre-op blood work.

I would seriously consider having her spayed.
If she isn't, she will have a 26% chance of getting mammary cancer.
If she is spayed before her first heat, she will have less than a 0.5% chance.
Pyometra is not uncommon in unspayed females and the treatment of choice is an emergency spay which is quite a bit more dangerous with a raging infection going on. So just some things to think about...
