“She is a bad mother if she didn’t keep the kid’s sandbox covered”
Bad? I don’t think so. The pet owner, who allowed their animal to roam over property they did not own is the “bad mother”.
The point is there are other cats, birds, etc. in the world; so many ways to get a sandbox contaminated unless she is going to guard that sandbox 24/7 she needs to have it covered to protect her children.
I said the cat owner was wrong as well.
