In a group of pet rats, social dynamics are quite fascinating to observe. Rats are social animals that establish hierarchies within their group. Typically, there will be a dominant rat that asserts its authority over the others through behaviors like grooming, scent-marking, and sometimes even aggression. Subordinate rats will often display submissive behaviors such as grooming the dominant rat or avoiding conflicts. It's also common to see strong bonds and cooperation between group members, with rats engaging in activities like mutual grooming and huddling together for warmth and security. Overall, pet rats form complex social structures that are essential for their well-being and emotional health.
