Parents need to know that there are old-fashioned values here. Children are smacked and switched, and boys are rambunctious.
Violence & scariness:Animals are eaten; children are smacked and hit with a switch. Various kittens and bunnies are captured to be eaten (though they always escape). Mr. Tod's house has "rabbit bones and skulls, chicken legs, and other horrors."
I am a huge Beatrix Potter fan and this book is really an essential element on a child's bookshelf. I should note that the risk of being eaten is a popular theme in this series and some children may find this disturbing. However, it should not be too frightening to most children. In any case, parents can easily skip the tales their children may find disturbing.
