Michele, I think it's a great idea and I hope if you go ahead with it everything comes out well. Based on what I've seen on the site (of what I remember at least) you seem like the type of person who would really care about the well-being of the animals. I'm currently studying psychology at University but if that doesn't work out I'd consider getting some business training and see if I can start up my own little pet shop. I wouldn't be surprised if it's more work than psych though, but it's worth a try.
