Sure, there are lots of good animal-welfare-related reasons to spay and neuter your pets. But can we talk about the best reason? BALLS ARE GROSS. At least, that's the contention of Katherine Heigl, who is clearly embarking on some kind of weird image-correction campaign where she embraces her reputation as an ice queen in order to show people that she's actually got a sense of humor. Or I guess possibly she just really, really hates balls.
