My cat Joey loves any kind of motion displayed on the screen.Especially bright colored ads. I can't display any
fish video, he would scratch up the screen. I noticed some battery operated fish at CVS this week.

much more realistic than the ones in the link. They have all the motions of real fish & they are in a bowl rather
than a screen display. I was thinking of getting them for Joey & Mikey. I'd rather clean up spilled water than deal
with a scratched up monitor.
