I've pet sat for these people twice before (one being for almost 10 days). Both are vets (one of them is a neuro resident at the school). It is a great money maker on the side, I totally agree. They pay quite well, otherwise, I wouldn't be over here. It is hard to find people who will let you bring your own pets, I agree. So, I don't pet sit /too/ often. I'm going to check out those sites, though! Thanks!
PS- I'm not watching or having anything to do with the football game today, either. Just myself, all the animals, doing some studying, and marathoning adventure time (I kind of have a problem xD)
