I am doing some research into getting a pet. I would like to get one in the summer, just before my DDs 4th birthday. I am really drawn to rats as have had some friends who have had them as pets and I think they are really lovely, good fun and affectionate. I also like the fact that you can toilet train them and teach them tricks. I have done a bit of online research and gather they need company and that they like to be housed in a part of the house that has a lot of action. I am thinking of putting them in my living room. My concern is how much they smell. Are they smelly or do you not really notice it so much?
