On the other hand, bacterial and parasitic illnesses can be transmitted, such as coccidia, giardia, and leptospirosis. Those things need to be taken seriously as we can get them from our squirrels or give them to our squirrels. Thankfully, it does NOT happen easily and in 12 years of rehabbing it's never happened to me.
