Cats are creatures of habit and typically react negatively to changes in their routine or environment. Such alterations can lead to stress, anxiety, and behavioral issues. Signs of discomfort may include hiding more than usual, decreased appetite, increased vocalization, or changes in litter box habits. It's important to introduce changes gradually and provide a comforting and stable environment to help ease their transition. Providing familiar objects like toys or blankets can also help mitigate stress and make adjustments smoother for your feline friend.
