Claudia Vinke, a veterinarian at Utrecht University in the Netherlands, participated in the research on the stress level of cats in shelters. In an animal shelter in the Netherlands, Fink divided the new cats into two groups, one group prepared boxes and the other group did not. As a result, she found that there was a significant difference in stress levels between the two groups of cats. In fact, a group of cats with boxes can adapt to the new environment more quickly. They are much less stressed than the other group, and they are more interested in interacting with humans. When almost all cats feel nervous, the first thing they do is hide. If this is taken into account, it is not difficult to understand. "Cats' behavioral strategy in coping with environmental changes and stress factors is hiding," Fink wrote in an email.
Another thing to note is that cats are very bad at conflict resolution. Domestic cats: the biological theory of their behavior: "cats don't seem to have developed conflict resolution strategies like other animals who prefer to live in groups, so the way they avoid tit-for-tat scenes is to avoid each other or reduce their activities."
