"Let's live in friendship, kids."
- All There in the Manual: Grey and White's names were mentioned only in scripts and merchandise rather than the cartoons themselves.
- Amusing Injuries: Averted for the most part, but played straight during the sillier parts of an episode when Toon Physics take over.
- Animation Bump: The first series used the cut out format with a drastically different design style, and may come off as downright creepy. The following cartoons were hand drawn with much more cuddly Golden Age style designs and usually got slightly more fluid with each one.
- Actual Pacifist: In the third series. You can prank Leopold all you want, the most he'll do is turn the prank around back on you, with brilliantly hilarious results.
- Beware the Nice Ones: Downplayed case. There are occasions Leopold will fight back, but he rarely takes it a very violent extreme.
- Played straight in the first episode, where, due to the influence of miracle tablets, he undergoes a Jekyll and Hyde transformation and beats the mice senseless for their earlier abuse.
- Cats Are Mean: Gloriously inverted starting with the third series. Leopold positively gives Danny a run for his money.
- Defeat Equals Friendship: At the end of each short, the exasperated mice admit defeat and apologise to Leopold, leading to his Catch-Phrase. Most evident in the last episode, where they actually join in on it.
- Easily Forgiven: As his catchphrase at the end of each cartoon epitomises, Leopold never shows hard feelings towards any of the chaos the two mice try to cause for him.
- The Everyman: Leopold. There's rarely much significant about him aside from how alarmingly nice he is.
- Funny Animal
- Early Installment Weirdness: May be the case with the first series, as it looks depressing from what evidence can be gleamed from Youtube today. Just LOOK at poor Leopold!
- The Fool: Most of the time, Leopold wins obliviously, sabotaging the mice's pranks by mistake or failing to notice them backfire from bad luck or incompetence on their part.
- Hakuna Matata: The opening song to "The car of Leopold the Cat" is impossible to listen to without breaking into a smile. It's a song about being cheerful and everything going well because you have a good attitude. That you must never loose your good nature, even in bad times "keep your tail up" and always believe in yourself, if you do that you will "move mountains". Alexander Kalyagin's kindly, optimistic nuncle voice definitely helps. Can be heard here: "The car of Leopold the Cat"
- Hero Antagonist: Leopold is very laid back, not making him a very proactive hero of the story. As such the focus is usually on the mice failing to harass him.
- Laser-Guided Karma: Every single time with the two mice. They try their damndest to have fun at Leopold's expense, only for their pranks to continually backfire at them.
- Mood Whiplash: In the absence of subtitles, non-Russian speakers can only assume this with the episode where Leopold gets "miracle tablets" from a random physician appearing out of nowhere seemingly by magic. The rest is Leopold going on a musical rampage tormenting the mice for what they did to him just minutes ago.
- Nice Guy: Leopold.
- Once an Episode: The mice will inevitably apologize to Leopold at the end of an episode, to which Leopold responds with his catchphrase.
- Screwy Squirrel: The mice try to be this.
- Squashed Flat: The mice, again.
- Talking to Himself: Gennady Khazanov voiced all roles in the first series, Andrei Mironov voiced all roles in the second series and Alexander Kalyagin voiced all roles in the series from third to tenth.
- The Voiceless: Averted in the first series. In the more recent series, dialogue is very minimal, limited majorly to the catchphrase, whispering between the mice and conversation from random characters appearing at the time.
