Any other mammals in which mammary gland have been sexualized?

As I understand it, it’s a common phenomenon for a trait attractive in the opposite sex, to be even more attractive when exaggerated.

I think you’re talking about superstimulus.

… scientists painted a picture of a female lizard the size of a car and the males gathered at it in preference to actual females.

An episode of the PBS science show NOVA showed an Australian beetle species whose males were sexually attracted to large and orange females—the larger and oranger the better. This became a problem when the males started to attempt to mate with certain beer bottles that were just the right color. The males were *more *attracted to the bottles than actual females.
