Quoting khigh:" Rats. Hands down, no question. DD has had some in her room since she was 2, they sit on the couch and ... [snip!] ... with us (with their own bowl of popcorn), and act like kittens all the time. The only problem with rats is they die too young."
See, I've heard really good things about rats. I hadn't ever considered them, but when I started researching they seem like great options. Guinea pigs are bigger, but it seems like rats are less frightened and more interesting to watch.
Honestly I'm between rats and snake. I like the idea of a snake, something they can watch that is in a closed tank. Also, they seem pretty dang easy to care for. But I really have a soft place for furry animals.
There are two cute little boy rats at the shelter and I really want to go down and see them and maybe adopt them.
