Please help me decide what I should do in this situation?

So I have been in a tight relationship for about 2 years with this girl and we are about to take it to the next level. Anyways 6 months ago we started living together, you know normal procedure. Now I don't have any pets at home (apartment) but my girlfriend told me it would liven up the house if we got a cat. She agreed to take care of it and other than the up front cost, she would take care of most of the financial needs. Than a month and a half ped and then she wanted a snake, which was followed up by a gerbil, rabbit and finally a handsome Anatolian Shepherd dog. She mentioned and made sure each time we got a pet that it was a male. Now I live in a zoo but its really no problem because we're on our way to getting a house. The only problem I have is that, my girlfriend is not that computer savvy and thus always forgets to log out of things like facebook and yahoo and stuff like that and so I was looking through my history for a youtube video I had seen a while back when I came across a bunch of bestiality web sites. Come to think of it, especially the snake, the house was starting to stink up and I thought it came from having all these animals indoors. I am very confused at this point, I don't know what to do...should I set up secret cameras while I'm gone for work? In any case, girlfriend is suggesting we get an armadillo next...
