Some cats may seem to be more vocal than others due to their personality and temperament. Some cats may be naturally more vocal and may be more likely to meow or purr to communicate their needs and emotions. Additionally, cats may be more vocal when they feel stressed or anxious, or when they are trying to get their owners' attention. Providing cats with a safe and comfortable environment and engaging in activities such as playing and cuddling can help reduce stress levels and encourage cats to be less vocal.
