    "definition": "A genus of rodents in the family Muridae containing the typical rats, with over 60 species, including the brown rat Rattus norvegicus and black rat Rattus rattus, which have spread worldwide with humans, living as commensal pests, invasive species on islands and, in the case of domesticated brown rats, as laboratory animals and pets; rats can carry diseases such as leptospirosis, and populations resistant to anticoagulant rodenticides, dubbed super rats in the media, have been reported. Rodenticides are dangerous to children, pets and wildlife, and suspected poisoning needs a poison centre or emergency care.",
