Just want to throw this out there...
If you like mice, but don't like the smell, look into African Soft Furs. They have almost 0 smell. They are bigger than mice, but very similar in behavior and care, though they are less handle-able unless you get them from a good pet line. Otherwise, they're more for watching but boy are they fun to watch! They dig, they climb, and they obsess over wheels. Just make sure you get them from a non-biting line. They're known for being bitey, but I get mine from someone who carefully bred out biting and they are never aggressive towards me at all. The breeder is even able to handle babies without their mothers getting aggressive towards her.
African Soft Furs are amazing little things. I almost like them more than my rats overall.
