I had a young lady who worked for me who kept pet rats. She thought they were great. Nothing to do with hiring her. I hired her because she was so smart I thought I might end up working for her some day. That didn’t happen but she was great and very successful.
I like bats also, but not in or on my house. I’ve had bats in my house twice and found an exterminator who didn’t exterminate. They had “no harm” techniques for getting and keeping them out of the house and ensuring there was sufficient attractive nesting space nearby for them to relocate. I’d do that again.
