Thank you all for your suggestions. I still have the cat. I removed one end of the light and dried as much as I could with a paper towel, then let it sit out for a couple of days to dry. I turned on the light and it came on. At that point I thought everything was good, however, I noticed a redder than normal reflection no the water. Apparently, several of my white LEDs failed to come on. Also, it appears that the blue LEDs are not working either. At least it was not a total loss. Perhaps the reduction in light intensity may help my algae problem.
