Common behavioral issues that cats may experience include excessive meowing, scratching furniture, and urinating outside of the litter box. To address these issues, it is important to identify the underlying cause. For example, if your cat is meowing excessively, they may be trying to communicate a need or desire. Additionally, providing your cat with plenty of mental and physical stimulation can help to reduce unwanted behaviors. If the issue persists, it is best to consult a veterinarian or animal behaviorist for advice.
