When it's getting late in the evening, Spot comes along and gets my attention in a "Time for bed" kind of way.
If I'm late waking up in the morning, Spot goes out of her way to ensure that I'm up and out of bed. Of course this is discounting her belief that if the big fat man doesn't leave the apartment then she won't be assured of being fed delicious kibble and wetfood now and again. Let us not forget that the big fat man usually gives her a scoop of kibble in the morning so she doesn't waste away during the day.
Finally when she's really annoyed she'll climb up into my arms, act all cute then viciously bite the tip of my nose.
Aaaaa
