You heard me. Rat groups. After I adopted my first pet rat, Ripley, in 2015, I took her home and realized I had no idea how to take care of her. While researching online, I stumbled into a thriving community of Facebook groups for rat parents. There are groups for sharing toys and cage decor, for matching rat foster parents with “forever home” adoptive parents, and for sharing related memes.
