How Long Can You Leave a Cat Home Alone? In Plain Words

Short answer: PetMD says healthy adult cats can generally be left alone for eight to 12 hours at a time. If you will be away for more than 24 hours, PetMD says to arrange for a pet sitter. PetMD also says you should not leave a cat alone for a week without daily care and supervision. Kittens need much shorter times alone — see the age guide below.
