Final answer:
The exact percentage of pet owners who value their bond with pets isn't given, but the bond is generally considered important, which can contribute to claims about mental health benefits and the advisability of pet ownership.
Step-by-step explanation:
The specific percentage of pet owners who believe the bond they have with their pets is important is not provided in the reference information. However, it is widely acknowledged that many pet owners value the bond with their pets, which aligns with the descriptive claim noted in the reference that having pets can improve mental health. This perception could arguably lead to the evaluative claim that people ought to have pets, illustrating what is known as the is-ought problem. To address the original question, broader psychological or sociological research could be consulted for statistical data on pet owner perceptions about their bond with their pets.
