disgusting sigma pi tradition

[kinney9]

Allright, so i found out something that really disturbs me and i do not know what to do about it!! I am in a sorority at a Michigan college that has a chapter of sigma pi at it. Well, i was at there house last week and it was their pledges "hell week" everyone knew this b/c of what they were wearing and how wasted they were. So anyway, i went upstairs to a personel brothers room that i knew to use the bathroom and i discovered two small boxes with rats in them. The extremly small boxes had not been cleaned in days and the smell was overwhelming. Needless to say i questioned a brother about this and since he was intoxicated he told me that during "hell week" the pledges have to carry a small animal with them at all times. He then proceeded to tell me stories about what they did to these animals, since the pledges become so recentful of them the all died. As an avid animal rights activist, i was horrified and sicken by the treatments of these small animals. One of the rats was completely hairless and i found out that the pledge had died it's fur so many times it fell out. Needless to say, i waited a little while longer in the night, and with the help of some of my sorority sisters, we stole the rats.
So now i do not know what to do. I don't want to cause trouble for my sorority but this is an absolutely disgusting "tradition" that i can not beleives continues today. Does this happen at other Sigma Pi chapters or is my school just lucky to have such an upstanding fraternity? Please, any comments or insights would be appreciated. I would also like to hear from other sigma pi's. Thank you for taking the time to read this.
