Our cat Bisou knows how to beg. If he wants attention, if he wants food, if he wants to go outside he has no qualms about getting in front of my face while Im working and just start begging. He does the sad eyes, the gimpy face, the serious boy, the needy look, you name it he knows it and does it.
The next photo is a classic photo of him getting his way. He wanted on the bed so we let him. Ohhh man he is stretching out and just relaxing! Pure bliss!!
