Designed for more advanced students, the CatWorks CD-ROM offers the user an opportunity to perform exciting, highly accurate, electronic dissections of the common house cat. Through the use of special cursors and buttons, the user is actually able to "dissect" nearly all areas of the cat's anatomy. QuickTime movies show selected portions of actual dissections along with voice descriptions of the procedures being performed. CatWorks certainly offers an excellent alternative to sacrificing an animal, and it can serve as a perfect pre-lab activity or post-lab follow-up to other types of laboratory activities and without the dangers of preservatives and sharp instruments. Without a doubt, this will rapidly become a "must-have" item in every well-equipped science classroom. Windows XP, Vista, & Windows 7.
