“My cat is being difficult” is one of the most common lines I hear as a clinical feline behaviorist, and it’s usually pointing to something deeper than “bad behavior.” I’m joined by Dr. Zazie Todd, psychologist, animal behavior expert, psychologist and author of Purr: The Science of Making Your Cat Happy, to unpack what’s really going on when cats swat, bite, hide, scratch the wrong things, or seem moody and unpredictable.
We get practical fast: how to set up your home for feline well-being with simple hiding spots and perches, how boredom shows up in indoor cats, and why choices and control matter so much to cat welfare. We also dig into reward-based training and clicker training, including how to teach a cat to feel safe in a carrier so vet visits don’t turn into a wrestling match. Along the way, we talk about why punishment and dominance myths harm the human-cat bond and can increase fear, anxiety, and aggression.
Then we zoom in on communication. We break down the body language that people miss, why the “belly flop” isn’t always an invitation, and what to watch for when petting turns into overstimulation. If you live with multiple cats, we cover how to tell real fighting from play by looking for role swaps, loose bodies, pauses, and whether claws are out. We also share where feline behavior research is growing and what we still need to learn, especially about kittens and socialization.
