Tropes present:

 * Action Mom: As a former circus performer, Lana is very athletic. The first episode alone has her swinging on a trapeze just to capture a spider.
 * Awkward Father-Son Bonding Activity: Part of the plot to the first episode involves Leo trying to find something that he and Spencer can do together, resulting in many of these.
 * Barefoot Cartoon Animals: Lana and Judy.
 * A Boy, a Girl, and a Baby Family
 * Dom Com
 * Dreadful Musician: Double-subverted. Spencer can play guitar very well, but he can't sing.
 * Family Theme Naming: The other four family members (besides Leo) are named after movie stars.
 * Fully-Dressed Cartoon Animal: Spencer and Kate.
 * Furry Confusion: In the first episode, Kate is shown to be a horseback rider.
 * Half-Dressed Cartoon Animal: Unlike the rest of the family, Leo wears only a sweater.
 * Hot Mom: Lana.
 * Lions and Tigers and Humans, Oh My!: Literally. The Lionheart family seem to be the only furries in an otherwise all-human world.
 * In the first episode, Kate's riding club otherwise consists of humans.
 * Thematic Theme Tune: "Roar".
 * Through a Face Full of Fur: Lana, when one of Kate's friends mentions Lana being a former circus star.
