Time to Clean Up

Visitors to Pacific Science Center may notice that there are fewer chambers in our naked mole-rat exhibit then there normally are. We are in the process of an extensive and systematic cleaning process that will last for 18-20 days


Our colony undergoes a “super-clean” about two times a year. Their chambers are cleaned and thoroughly disinfected every day for a three week period.

The purpose of this cleaning process is to remove and kill any harmful bacteria or viruses that can exist and build up in the colony. The naked mole-rats are a bit more crowded at this time, and it means they are less visible to our guests. But in the end, it will lead to better health for all of the members of our mole-rat colony.

Thanks for your patience!
