My two cats aren’t pets, they’re family. They each have their own personality, needs, and forms of communication. My older cat loves her sunny spots, chin scratches, cardboard scratching sled, and mint-sticks but will never chase after a toy (just treats). She has her routine and sticks to it. My younger cat is simultaneously skittish and demanding of butt-pats. I just need to pay attention to what she’s communicating. If it moves, she’ll chase it. Your cat would be like another family member with their own personalities that need to be learned and adapted to. Like cats, dogs have their own personalities and communication styles that need to be learned and understood. But there are also extra considerations depending on size and breed. Working dogs need exercise, games, and puzzles to solve. Some breeds just need to know you’re there for them. As a sitter, I would expect the owner to train their dog and make sure they have access to the space they need. As an owner, you should expect me give them the exercise, attention, and affection they need while maintaining the discipline you’ve taught them.
