Feliway IS a calming spray, made from the 'friendly' hormones that a cat gives off when it head rubs/bumps things.

If a cat is peeing because of stress - many do - then that is why it is used. It calms the stress, and HOPEFULLY the peeing stops.

Clomicalm is a med - but don't know if it is in a spray. Medusa knows about it.

Good luck!
