I am surprised at the demographic here. Im a 22 year old guy finishing up undergraduate here in Texas. Ive had Calico for about 5 months, next saturday im going to the Texas Rustlers Guinea Pig rescue (Anyone from the area, this place is amazing, check it out.), hopefully to get her a baby sister. Despite the poll results, it seems us men have come out guns blazing in this thread pronouncing our minority.
As harry mentioned, there is a strong appeal in the way of building things for the cages and coming up with ever more elaborate systems of comfort and delight for ones little charges. The guy who rigged up and old PSU for piggie-AC set me off for hours thinking up things I could do with my mountain of discarded computer parts.
Stay strong, brothers
