The only part I didn't like

I think I've seen every episode of Malcolm in the Middle and throughly enjoyed the show. Some episodes are better than others, but there's only one part I didn't like at all. I think it's in Season 7, where the evil Ida is pitting Malcolm and Reese against each other for the love of a girl. They go through a series of bizarre tests, one of them is putting both guys in a bag with a cat and an attack dog fighting each other and they have to get out. You can hear both the cat and dog growling and hissing at each other. I'm sure the producers filmed the scene without any harm to either animal, but it was so disturbing hearing both fighting and wasn't very funny. That scene made me hate Ida even more as she was just a Nazi bigot. Does anyone know the name of the episode or what I'm talking about?
