Common Sense Note
Parents need to know that this animated classic is far from educational. Although it's considered a masterpiece, some of the series' content -- particularly the consequence-free cartoon violence -- is iffy for younger viewers. There's also some content that reflects the series' original 1960s' era -- such as the fact that the characters smoke in some episodes.
In one instance, Jerry uses a bra as a parachute.
Cartoon violence aplenty -- guns, knives, saws, axes, and explosives are used regularly (usually with little to no lasting consequence).
Yes, it's all in fun, but Tom and Jerry do promote unhealthy competition and poke fun at stereotypes. Violence is consequence-free.
Drugs / Tobacco /
Jerry smokes a cigarette; Tom smokes a cigar. The series was made in the 1960s, so this was fairly typical of the time period.
