Our big cat, who is named Little Bits because she was indeed little at one point, is a very insistent cat. When she decides that she wants pets and skritches, you are required to give them to her.
Joe says she's an unspeakable cat. I think the description is a riff on Warren Zevon's Excitable Boy.
She loves having her belly rubbed and rolls over on her back so that you can easily reach her ample tummy. (She may have started out tiny, but she's a good 18 pounds now.)
If you dare to stop for any reason, she will ensure that you know you're falling down on the job. Here's a picture of Little Bits reminding Joe of his obligations.
