In a previous article, we described our approach to implementation of effective environmental enrichment, which begins with the diagnosis of environmental features to determine how well they meet the behavior and welfare needs of indoor-housed cats. We formulate this diagnosis based on a pertinent history and physical evaluation. A pertinent history allows us to identify features of the cat and environment that may precipitate or contribute to observed behavioral and physical problems. Physical evaluation of the environment means determination of the presence and quality of physical and behavioral resources available to the cat. As discussed in the previous article, we organize the environment into five basic systems: physical, nutritional, social, elimination, and behavioral, and methodically investigate each one to identify any features that may benefit from improvement. Our first article offered practical means of meeting the environmental needs of cats within each system. The objective of this article is to present methods for reviewing the information obtained with the client and developing an effective implementation plan. Rather than blaming the client for any identified environmental shortcomings, we choose to emphasize areas of improvement that the client believes can be accomplished. Effective communication skills increase the probability of implementation of and adherence to the plan.
