Overhearing the radio, Tom discovers that it is 'Be Kind To Animals Week' and bakes Jerry a pie. While searching for the mouse, Tom discovers Jerry's diary and reads some of his entries. Cue numerous flashbacks to earlier cartoons in which the rodent repeatedly humiliates the poor cat. When Tom finally finds Jerry, he splatters the surprised mouse with the pie.In order to keep production costs down, many series resort to the 'compilation' episode, wherein characters recall moments from their previous adventures, thus allowing for the recycling of old footage; this is the first of several T&J cartoons to exploit this economic but rather lazy format, and as such it holds very few surprises for fans of the animated duo.

Okay, the story is quite light and perhaps not all that original, there were a few other Tom and Jerry cartoons than this that had this particular formula as well. But Jerry's Diary is still a very nice cartoon in many ways. It has many funny moments, and with the use of Solid Serenade, Tee for Two, Mouse Trouble and The Yankee Doodle Mouse(serving as part of the diary excerpts) it is somewhat of a nostalgic throwback which will delight anybody I think. The animation is wonderful, with luscious backgrounds and colours, as well as well-drawn characters, the pacing is crisp and the music once again does a great job with enhancing the visual gags complete with upbeat orchestration. Tom and Jerry are still as likable as ever with the writing and gags playing to their character strengths rather than going against them.All in all, very nice if not one of my favourite Tom and Jerrys. 8/10 Bethany Cox

This cartoon is one of the earliest forms of a 'clip show' that I have seen. You've seen (and no doubt been annoyed) the episodes of The Simpsons where they go 'remember when' before cutting to old footage, thus trimming down on the cost of original production. Well, that's what happens here.Tom is planning the usual amount of torture for Jerry when the radio warns him that it is 'Be Nice To Animals Day'. Convinced that he should be kind for once, Tom bakes the mouse a cake, grabs some presents and waits by his hole. But Jerry ain't home, and it's a perfect opportunity for Tom to grab his diary and reminisce about all the time the mouse got the better of him, cue the old footage.One to skip.

Tom, who has just set up a heap of traps outside Jerry's mousehole, learns from Uncle Dudley's radio slot that it is 'Be Kind To Animals Week', so he replaces the traps with gifts, only Jerry is not in. Tom spots Jerry's diary on the desk and sneaks a peek at some of the entries (cue excerpts from previous cartoon in the Tom & Jerry series). Unfortunately each entry Tom reads reminds him of an occasion where he is on the receiving end of punishment, which gradually increases his anger. Will he be able to stay kind to Jerry or will his declining patience get the better of him?Very enjoyable, if 'economic', entry to the series.
