Saint Faustina prayed the Rosary every day. One time, she wrote:

… [One time] I saw many demons. One of these tried to vex me; taking the form of a cat, he kept throwing himself onto my bed and on my feet, and he was quite heavy, as if [weighing] a ton. I kept praying the rosary all the while, and toward dawn these beings vanished, and I was able to get some sleep. (412)
