Q. I have a 9 week old kitten. At what age do they start spraying? We have a 12 yr old cat that has sprayed a door, I think. Could it be the kitten?

Answered By
AMANDA MILLER COOK

A. It is not unusual for an established house cat to start acting out once there is a change in his environment. In this case, the new kitten could be a stressor for the older cat as he tries to get used to the new change of an added house member. To answer your question, cats generally do not start spraying until the are around 5-6 months old.
