Dont mix ANYTHING. All of those animals in that room need to be taken care of individually, and SERIOUSLY lock everything down. Dont touch an edge of the rack without washing your hands first and after.

Seriously. Consider this as a worst case scenario. Dont touch your pants, dont touch anything, use gloves. Throw gloves away after EACH animal. Use gloves for EVERYTHING in that room. Even touching the Door handle if you have one on it. consider everything dirty and carrying the virus.

Avoid touching anything sick as much as you possibly can.
