Don't feel guilty about having Little C spayed. By doing so, you just about eliminated her chance of ever getting a mammary tumor. You also have lessoned her chances of ever getting the following:

Breast cancer
Cystic endometrial hyperplasia and pyometra
False pregnancies
Mastitis (can occur during false pregnancy)
Transmissible venereal sarcoma
Ovarian and uterine tumors
Cystic ovaries and hyperestrogenism
Chronic endometritis
Vaginal hyperplasia and prolapse
Uterine torsion or uterine prolapse

This is a good article about understanding bloodwork to print out and save for future reference:

This is what it says about BUN:

UREA NITROGEN (BUN)

Normal Range 9 - 27 mg/dL

BUN is produced by the liver and excreted by the kidneys. Decreased levels are seen with low protein diets, liver insufficiency, and the use of anabolic steroid drug. Increased levels indicate any condition that reduces the kidney's ability to filter body fluids in the body or interferes with protein breakdown.
