Loaf

Loaf is Grill's cat, and can be seen in to the side of him on his computer in his videos.

Loaf was introduced in the Invisible Bathtub episode of his show, the Grill Channel,  and was introduced when he rescued their (Loaf's) image from a 3D tour of a hoarder's house. "Loaf was named by fans for the fact that when Grill saw him, he gasped and exclaimed, 'KITTY! Hey there, guy! Aren't you just the most precious loaf?!'""Later in the episode, he copy- pasted the image of Loaf onto the surrounding lawn of the house, freeing him as he had promised. The current picture of Loaf is a drawing."
