Both were irresponsible. She is a bad mother if she didn’t keep the kid’s sandbox covered...even if that cat wasn’t able to mess in it there are more cats in the world. The cat owner is a bad owner to allow the cat to be loose to keep messing in the sandbox.

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”.
