What is one implication of poor handling practices on a cavy?

Poor handling practices can lead to increased aggression in a cavy for several reasons. When cavies are not handled gently or regularly, they may feel threatened or stressed, which can contribute to fearful or aggressive behaviors. Consistent, proper handling helps to build trust between the handler and the animal, making the cavy more comfortable and less likely to react aggressively out of fear or discomfort.

In contrast, the other options suggest outcomes that are typically not associated with poor handling practices. For instance, improved coat texture and better feeding habits are linked to proper care and management rather than negative handling experiences. Additionally, larger physical size is generally a result of genetics and nutrition rather than the handling practices employed for the cavy. Hence, the connection between poor handling and increased aggression is a significant one, demonstrating the impact of human-animal interactions on behavior.
