Final answer:
The information provided does not directly answer the question regarding the percentage of pet owners with a strong attachment to their pets, but it highlights the emotional significance of pets in different cultures and human-animal relationships.
Step-by-step explanation:
The question seems to refer to how strongly pet owners feel attached to their pets. However, the information provided does not specifically answer the question about the percentage of pet owners who classify their attachment to their pets as strong. Instead, it gives insight into the cultural significance of pets and how humans relate to them, as well as statistical data on the ownership of items like stock and smartphones as a reflection of cultural trends.
For instance, Yi-Fu Tuan's studies highlight that the relationship between humans and pets can involve strong emotional bonds in Western societies, partly due to people's growing distance from the natural world. In contrast, the relationship between humans and animals in other cultures can be less about ownership and more about mutual respect and reciprocity.
The question about the percentage of pet owners who have a strong attachment might be better addressed through direct survey data or psychological studies on human-animal bonding rather than through the information provided.
