On the front cover of this birthday greeting card, envision an abstract composition that merges the whimsical essence of a cat with the geometric precision and vibrant palettes inspired by the masters of abstract art.

**Background**: The backdrop is a soft gradient reminiscent of a Rothko painting, transitioning from a deep indigo at the top to a warm coral at the bottom. This creates a dynamic tension, mimicking the dawn of a new day—symbolic of the celebration of a birthday.

**Central Focus**: Positioned slightly off-center, a deconstructed representation of a cat, using the principles of Suprematism by Kazimir Malevich. The cat is composed of a series of overlapping geometric shapes: a square for the body, a triangle for the ears, and a series of intertwined curves suggesting the tail. The forms are colored in bold, contrasting hues of cerulean blue, sunflower yellow, and poppy red, echoing Mondrian’s color scheme, yet with a more playful twist.

**Foreground Details**: Scattered across the card are gestural, swirling lines akin to Pollock's action paintings, yet more restrained, suggesting the playful movement of the cat. These lines are painted in metallic gold and silver, adding a subtle shimmer that catches the light.

**Additional Elements**: Floating amidst the composition are small, whimsical shapes inspired by Joan Miró. Think abstract stars, crescent moons, and irregular circles in pastel shades of mint green, lavender, and peach, providing a sense of celebration and wonder.

**Borders**: The card’s edges are adorned with thin, intersecting black lines, nodding to Agnes Martin’s grid work, giving a structured frame to the lively, colorful chaos within. These lines intersect at varying angles, some sharp, some gentle, echoing the unpredictable nature of a cat’s play.

This abstract symphony of shapes and colors crafts a unique and captivating birthday greeting card cover, inviting the viewer to celebrate the joyous and unexpected elements of life, much like the companionship of a cat.
