Can rats catch human diseases?
Rats can catch strep throat from people, and are sensitive to other respiratory bacteria and viruses as well (such as colds, flus, etc.). If not treated, these may escalate to pneumonia. To prevent this, never let anyone who is sick (including you) hold or be near your rats much, and even when you aren’t sick, wash thouroughly with disinfecting soap or wipes before and after handling your pets.
