Meghane, could you provide a link?
I remember a year or two ago you referenced a study that concluded that every heat cycle experienced by an intact female increases the chances of that animal contracting mammary cancer later in life. At least that's what I *think* I remember. If available (and if my memory hasn't completely distorted this), would you please provide a link to that study or provide the source of the study? It's something I'd like to have handy to pass along to folks who are waivering on the "should I, shouldn't I have my animal spayed" debate.
