Abstract: NMDA receptor antagonists can be used in methods of treatment, for reducing the frequency of stereotypic behaviors in animals and for reducing the frequency of analogous compulsive behaviors in humans, for example, those that have been said to be a manifestation of, or related to, obsessive-compulsive disorder. Of particular interest is the non-competitive NMDA receptor antagonist memantine.

Abstract: A system and method for automatically applying an odor neutralizing or masking agent or a pheromonal agent to a cat litter box, or an odor neutralizing or masking agent to an area around a human toilet. There is a source of spray delivery of the agent, and a motion sensor. The spray delivery source applies the agent in response to the motion sensor, so that the agent is applied only after the cat or human has finished using the facility.
