Brick Cat MOC: Round Face, Curvy Body, Movable Tail
Here is the short version: a cat MOC looks cute when the face is round, the features are clustered tight together, and the body tapers through staggered layers. Sitting poses photograph best, and the movable tail comes from a ball joint plus hinge bricks.
Cats are probably the most comforting subject in brick building: round face, big eyes, a plump body, and the model lifts your mood the moment it sits on your desk. Yet plenty of first-time builders end up with something that reads as a cube, or worse, a fox. The good news is that cuteness follows rules. This guide walks through the key steps, from face shape and features to body curves and an articulated tail.
Face Shape and Features: The Secret Is Round and Clustered
Two things make a cat face cute: the face is round, and the features sit close together. For the face plate, build the outline from four 2x3 curved corner bricks so it is wide at the bottom and narrows toward the top, then close the forehead and chin with 1x2 slope bricks so no right angles show. The eyes carry the whole expression. Use black 1x1 round tiles and keep the gap between them within 2 studs, because the closer they sit, the more that small-but-fierce look comes through. Place the eyes slightly below the midline of the face plate; that is the trick behind a kitten-like face. For the nose, turn a pink 1x1 tile upside down, and build the mouth from 1x1 slope bricks so it tilts up just a little. Whiskers can be two thin rods held in 1x1 clip bricks, or you can simply use a printed face piece with whiskers and save yourself the trouble. Leave SNOT studs facing up inside the head so you can add ears later and fine-tune the height of the features; that is what keeps the expression lively.
Body Curves: Round Shape Comes From Staggered Edges
A boxy torso is the most common failure in cat MOCs, and the rounded body is where the real skill shows. Do not run the sides straight up and down. Instead, step each layer outward by one stud with 1x2 slope bricks, then draw it back in layer by layer so the transition forms a natural arc. Cover the back and hindquarters with 1x3 curved bricks, and recess one column of studs at the belly, and the slightly bulging pear-shaped curve appears immediately. For the white chest bib, ring the neck with 1x2 tiles; it uses few parts and adds depth. If you want a fuller body, fill the interior with solid bricks and then wrap a layer of tiles over the surface, which keeps the finish clean and feels better in the hand.
Sitting, Lying and Standing: Three Poses, Three Frames
The skeleton differs a lot between poses, so decide the pose before you start building. Sitting is both the most photogenic and the simplest: bend the hind legs backward with 1x2 hinge bricks to form the seat, drop the front legs vertically to the ground, and tilt the torso forward about 15 degrees, with the tail curling naturally around to the front. Lying down suits a flat, wide face: spread the torso horizontally, support all four legs with short axle pieces so the body sits 2 plates off the ground, lift the head slightly and bring the front paws together. Standing is the hardest to keep stable: raise the legs with 2x2 bricks, widen the paws with 2x3 plates, keep the center of gravity inside the rectangle formed by the four legs, and consider adding a transparent support rod so the cat does not end up doing the splits. Whatever the pose, build the skeleton before the skin: legs and hinges and spine first, then fill the torso, then wrap the curved shell over it.
Movable Tail and Ears: Bringing the Cat to Life
The articulated tail is the soul of a brick cat MOC. Connect the base with a ball joint piece so it swings up, down and side to side; add a hinge brick every 3 to 4 studs along the length, and the whole tail can hold a natural curl, with a cone piece tapering the tip. For the ears, use 1x1 triangular bricks or small slope bricks plugged onto the upward-facing SNOT studs on top of the head, and put a 1x1 hinge plate at the base so each ear can rotate slightly. That detail alone lets you act out the startled airplane-ears expression. Test every moving joint through two full turns before final assembly and check the resistance: too loose and it droops, too tight and it snaps.
Getting Instructions: From Parts to Finished Model in One Step
Designing a brick cat from scratch usually means taking it apart and rebuilding a dozen times while you slowly adjust the colors and proportions. The easier route is to start from a proven set of cat MOC instructions, then tweak the colors and expression to your taste. BrickPlan hosts a large collection of brick cat MOC instructions, each with a complete parts list and step-by-step build notes, so a beginner can follow along and have a satisfying desk cat finished in a single day.

FAQ
Q: How do I build a brick cat face that actually looks cute? A: The key is a round face with tightly clustered features. Build the face plate outline from four 2x3 curved corner bricks so it is wide at the bottom and narrow at the top, close the forehead and chin with 1x2 slope bricks, keep the eyes within 2 studs of each other, and set them slightly below the midline of the face plate.
Q: How do I get a rounded body on a cat MOC? A: Keep the sides from running straight. Step each layer outward by one stud with 1x2 slope bricks and then draw it back in layer by layer. Cover the back and hindquarters with 1x3 curved bricks and recess one column of studs at the belly to create the gently bulging pear shape.
Q: Sitting, lying or standing, which is easiest to build? A: Sitting is the most photogenic and the simplest: bend the hind legs back with 1x2 hinge bricks to form the seat, drop the front legs vertically, and tilt the torso forward about 15 degrees. Standing is hardest to keep stable, so a transparent support rod helps prevent the splits.
Q: How do I make an articulated tail that looks natural? A: Connect the base with a ball joint so it swings up, down and sideways, add a hinge brick every 3 to 4 studs along the middle so it can hold a curl, and taper the tip with a cone piece. Test each joint through two turns first, since too loose droops and too tight snaps.
