All was relatively well until about three a.m., when both cats decided it was time to be getting up. Bullet nipped at my nose and hands and Stretch pawed at my blanket. This went on for a while, as I adjusted myself to avoid the assaults. They both did settle again. Finally I did get up.
I can't say that I noticed that I got to sleep easier than usual last night, or slept better. But I will give this the longer try suggested - about 12 weeks.
