Indoor cat behavior is easier to understand when the home is set up around territory, escape routes, litter access, scratching, play, food, and predictable human routines. This hub starts with the environment before blaming personality.
Quick answer
A better indoor cat home gives the cat safe hiding, vertical space, scratching choices, clean litter access, predictable food and play, and low-pressure handling. Sudden changes in appetite, litter habits, hiding, movement, or vocalization should be treated as possible health signals before they are treated as behavior problems.

When to call a vet
Call a veterinarian for straining in the litter box, inability to urinate, repeated vomiting, sudden hiding, appetite loss, rapid weight change, breathing trouble, injury, or any sudden decline. Cats often hide illness, so new behavior deserves careful attention.
