  • Comparative Example 5 is harder than the break induction portion 24 of the base 2 of the pet food 1 of this embodiment. In other words, the pet food of Comparative Example 5 is less likely to break. In other words, it can be seen that the heart-shaped pet food 1 of this embodiment is more easily broken at the break induction portion 24 and easier to eat, despite having a larger planar shape than the pet food of Comparative Example 5.
