Very true.
For the same reason, I do not offer any wild rodents to my snakes.
I have no idea where they’ve been.
Some students at the high school I used to teach at released some large crickets in the hall. Of course, knowing I kept lizards, my vindictive chairman accused ME of bringing them to school and somehow they got out. Sure, teachers release crickets into the halls of schools all the time, right? I pointed out that all my species of lizards are small, and therefore do not eat large crickets, so I wouldn’t have bought large crickets, right? That shut him up.
