Subject: Reality Check From: Dan Tollin <tollin(at)PHYSIOLOGY.WISC.EDU> Date: Tue, 1 Mar 2005 16:37:30 -0600Hi, My cat prefers John Cage's 4'33" (which, of course, is 4 minutes and 33 seconds of silence) over just about anything else. I suspect rodents would prefer the same. Cheers, Daniel J. Tollin, PhD Assistant Professor University of Colorado Health Sciences Center Department of Physiology and Biophysics Aurora, CO 80045
