Catz 5 not opening

When I insert the Catz 5 CD-ROM into the CD-ROM drive, a window opens which contains options, such as "Play", "Uninstall", etc. When I click on the word "Play", another, smaller window opens, containing a loading bar and some adorable images of kittens and puppies. When the loading bar is loading, however, it only reaches approximately three-quarters of the way to the end, and then the window closes and the game does not open - nothing else happens at all, in fact. If I double-click the desktop shortcut to "Petz 5", it only opens the smaller loading window, and loads three-quarters of the way again, but at a much greater speed, and closes, yet again. I've tried multiple things, such as restarting the computer, wiping off the CD-ROM, and removing the disk then replacing it in the machine, but to no avail. Do you know of any possible cause for this, or any way it could be fixed?

Thank you for your time.

Best regards,
Blaahhh.
