I have the same question regarding my 6 1/2 mo girl, Zoey. Talked with the vet about growth plates and she said they are finished about 1 year of age. I asked why it was important to spay "before" her first heat and she said it was just a precaution to prevent pregnancy. Well, little Zoey is not going to get pregnant any time soon - not ever - and she weights 5 lbs. I think I will wait until she is 8 or 9 mos old and weighs a little more. She can just wear panties if she comes into heat before then. I think maybe with a male it show be sooner.
