This ain't no way to treat Tom and classifies as animal cruelty. Person who made that episode should have been banned from TV networks for lifetime.
Level of aggression in this episode is unbearable and doesn't compare at all to early HB episodes where black lady was the villain.
For me it appears that Gene Deitch had some kind of a grudge against cats and wanted to visualise his trauma on the screen. Maybe childhood trauma, I don't know, a psychologist should examine it. Otherwise I find no reason to picture Tom like this, no child watching this episode will learn good things from it, it only perpetuates vigilantism on cats.
