Growling is a low, rumbling sound often made by animals, particularly dogs and cats, as a form of communication. It can indicate various emotions, such as fear, aggression, or discomfort. When an animal growls, it may be warning others to stay away or expressing its displeasure. In addition to animals, humans can also produce a growling sound, often imitating animals or expressing frustration. This vocalization can serve as a playful gesture or a way to convey annoyance. Understanding the context of growling is essential for interpreting its meaning accurately.
