Crochet Cat Alien Plush Toy Amigurumi Pattern: Your Complete Guide to Making an Out-of-This-World Stuffed Companion
If you’ve been searching for a crochet project that’s equal parts whimsical, beginner-friendly, and completely irresistible, you’ve landed in the right corner of the universe. This crochet cat alien plush toy amigurumi pattern brings together two beloved things — the charm of a fluffy cat and the mystery of outer space — into one adorable stuffed creature you’ll want to make over and over again. Whether you’re crocheting for yourself, gifting it to a child, or building up an inventory for your craft shop, this pattern has everything you need to create a little extraterrestrial kitty that’s ready to be loved.
Amigurumi, the Japanese art of knitting or crocheting small stuffed animals and creatures, has taken the crafting world by storm for good reason. The results are compact, sturdy, endlessly customizable, and just plain cute. Adding an alien twist to a classic cat design opens up a world of creative possibilities — we’re talking antenna, extra eyes, unique color combinations, and all the cosmic details that make your finished plush feel like it beamed down from another galaxy.
Let’s get into everything you need to know.
What You’ll Need Before You Start
Before diving into the actual crochet cat alien plush toy amigurumi pattern, gathering your materials will make the whole process smoother and more enjoyable.
Yarn: Worsted weight yarn works beautifully for amigurumi because it creates a dense, firm fabric that holds its shape and hides the stuffing underneath. For this cat alien plush, you’ll want a primary color for the body — think something cosmic like mint green, lavender, electric blue, or soft lilac — along with a contrasting color for the belly, inner ears, and any accent details. A small amount of black or white yarn works well for facial features.
Hook: A 3.5mm to 4.0mm crochet hook is the sweet spot for worsted weight amigurumi. Many crocheters prefer going down a hook size from what the yarn label suggests, which tightens the stitches and prevents stuffing from poking through.
Safety Eyes: Two 9mm or 12mm safety eyes are the standard for a plush this size, but for the alien cat variation you can add a third eye right in the center of the forehead for extra extraterrestrial effect. If you’re making this for a child under three, embroider the eyes with yarn instead, since safety eyes can be a choking hazard.
Polyester Fiberfill: This is the stuffing that gives your amigurumi its satisfying squishiness. Don’t skimp — firmly stuffed amigurumi holds its shape far better and looks more polished when finished.
Stitch Markers: These are lifesavers for keeping track of the beginning of each round, especially since amigurumi is worked in continuous rounds without joining.
Yarn Needle: A blunt tapestry needle is essential for sewing pieces together and weaving in ends.
Wire or Pipe Cleaners (Optional): If you want the antenna to stand upright and pose-able, inserting a small piece of wire or a pipe cleaner inside each one gives them structure.
Scissors: Any sharp pair will do.
Understanding the Stitches Used
This crochet cat alien plush toy amigurumi pattern uses a small set of basic crochet stitches, making it accessible even to newer crocheters who are just getting comfortable with working in the round.
Magic Ring (MR): This is the foundation for most amigurumi pieces. It creates a tight, nearly invisible center that doesn’t leave a hole in the middle of your work.
Single Crochet (SC): The backbone of nearly all amigurumi. Every stitch in this pattern that isn’t otherwise specified is a single crochet.
Increase (INC): Two single crochets worked into the same stitch. This is how you make your pieces grow wider.
Decrease (DEC): An invisible decrease (also called an invdec) joins two stitches together into one and is how you shape pieces to taper inward. Insert your hook through the front loops of two consecutive stitches, then complete a single crochet.
Slip Stitch (SL ST): Used occasionally to close rounds or attach pieces.
Chain (CH): Used in a few places for creating small tabs or loops.
All rounds in this pattern are worked in a continuous spiral unless otherwise stated. Do not join at the end of each round — just keep going and use a stitch marker to track your starting point.

Crochet Cat Alien Plush Toy Amigurumi Pattern
The Head
The head is one of the most important pieces of your amigurumi because it carries the most personality. For this cat alien design, the head is round and slightly larger in proportion to the body, giving it that classic cute amigurumi look.
R1: MR, 6 SC (6)
R2: INC in each ST around (12)
R3: (SC, INC) repeat around (18)
R4: (SC, SC, INC) repeat around (24)
R5: (SC, SC, SC, INC) repeat around (30)
R6: (SC, SC, SC, SC, INC) repeat around (36)
R7: (SC 5, INC) repeat around (42)
R8–14: SC in each ST around (42) — 7 rounds even
R15: (SC 5, DEC) repeat around (36)
R16: (SC 4, DEC) repeat around (30)
Before continuing to decrease, this is the time to attach your safety eyes. Place them between rounds 10 and 11, approximately 7 to 8 stitches apart. If you’re adding a third center eye for the alien effect, place it centered between the two and one round above them. Begin stuffing the head firmly now, and continue adding stuffing as you decrease.
R17: (SC 3, DEC) repeat around (24)
R18: (SC 2, DEC) repeat around (18)
R19: (SC, DEC) repeat around (12)
R20: DEC repeat around (6)
Close the opening and fasten off, leaving a long tail for sewing. Weave through the front loops of remaining stitches and pull tight to close completely.
The Body
The body of your crochet cat alien plush toy is slightly smaller than the head, giving the finished plush that signature amigurumi charm.
R1: MR, 6 SC (6)
R2: INC in each ST around (12)
R3: (SC, INC) repeat around (18)
R4: (SC, SC, INC) repeat around (24)
R5: (SC, SC, SC, INC) repeat around (30)
R6–13: SC in each ST around (30) — 8 rounds even
R14: (SC 3, DEC) repeat around (24)
R15: (SC 2, DEC) repeat around (18)
R16: SC around (18)
Leave open for now. Stuff the body firmly before closing. You’ll sew the body to the head after all other pieces are assembled.
The Ears (Make 2)
Ears are one of the most defining features of your cat alien amigurumi. These pointed ears give it that feline silhouette.
R1: MR, 4 SC (4)
R2: INC, SC, INC, SC (6)
R3: INC, SC, SC, INC, SC, SC (8)
R4: INC, SC 3, INC, SC 3 (10)
R5: SC in each ST around (10)
Fasten off leaving a long tail for sewing. You do not need to stuff the ears — leave them flat. For the alien version, try crocheting the ears in a slightly different shade or adding a small accent color for the inner ear.
Inner Ear (Optional, Make 2): Using your accent color, create a small flat oval or triangle, embroider it directly onto the front of each ear before sewing the ears onto the head.
The Arms (Make 2)
R1: MR, 6 SC (6)
R2: INC in each ST around (12)
R3–5: SC in each ST around (12)
R6: DEC, SC 4, DEC, SC 4 (10)
R7–10: SC in each ST around (10)
R11: DEC, SC 3, DEC, SC 3 (8)
R12–14: SC in each ST around (8)
Stuff lightly — the arms should be soft and flexible rather than rigid. Flatten the opening and sew shut. Leave a long tail for attaching to the body.
The Legs (Make 2)
R1: MR, 6 SC (6)
R2: INC in each ST around (12)
R3–4: SC in each ST around (12)
R5: DEC around (6)
R6–12: SC in each ST around (6)
The first two rounds create a small round foot, and then the tube continues upward to form the leg. Stuff the foot portion firmly and the leg portion lightly. Flatten the top opening and leave a long tail for sewing.
The Tail
R1: MR, 4 SC (4)
R2–16: SC in each ST around (4)
The tail is a simple tube. You can stuff it very lightly or leave it unstuffed for a flat, floppy look. Curl it slightly before sewing it onto the back of the body for a natural cat pose.
The Antenna (Make 2 — The Alien Feature!)
This is what takes your cat from ordinary to intergalactic. These little antenna are one of the most fun details of the whole pattern.
R1: MR, 4 SC (4)
R2: INC in each ST around (8)
R3: SC in each ST around (8)
R4: DEC around (4)
R5–12: SC in each ST around (4)
The ball at the top forms during rounds 1–3, then tapers down and continues as the antenna stalk. If you want them to stand upright, insert a small piece of pipe cleaner before closing. Fasten off and leave a long tail for sewing onto the top of the head.
Assembling Your Cat Alien Amigurumi
Assembly is often where amigurumi beginners feel the most uncertain, but with a little patience it becomes one of the most satisfying parts of the whole process.
Start by pinning all your pieces onto the body and head before sewing anything permanently. This lets you adjust placement until you’re happy with the overall look. A general guide for placement:
The head should sit centered on top of the body, with the bottom of the head slightly overlapping the top of the body opening. Sew all the way around using your long tail and a yarn needle, pulling the yarn through corresponding stitches on each piece. Go around twice for extra security.
The ears sit on top of the head, roughly between rounds 1 and 5, angled slightly outward. Sew them down along their entire base — ears that are only partially sewn tend to flop in unflattering ways.
The arms are attached to either side of the upper body, just below the neck seam. Angled slightly downward and forward looks the most natural.
The legs go on the bottom of the body, positioned toward the front so your cat alien can “sit” upright on its own if balanced properly.
The tail attaches to the back lower body. Curl it to one side for a relaxed, playful look.
The antenna go right on top of the head, placed symmetrically on either side of center. Space them about 5 stitches apart for a balanced look.
Adding the Face and Final Details
The face is where your cat alien plush truly comes to life. Beyond the safety eyes you already placed, a few simple embroidered details transform a blank round head into a personality-filled character.
Use black yarn or embroidery floss to stitch a small nose — a simple triangle or a tiny Y-shape both work beautifully. Add a gentle curve beneath it for a subtle smile, or leave the mouth absent for a more mysterious, alien expression.
Whiskers can be added using stiff black thread or thin wire — pull them through the cheek area and knot them on the inside before trimming to length. Three whiskers on each side is traditional, but two feels sleeker for the alien variation.
For extra cosmic flair, try adding small embroidered stars or dots around the body using metallic or contrasting yarn. Some crocheters love to add blush to their amigurumi cheeks using a bit of makeup blush powder and a small brush, giving the finished plush a warm, rosy glow.
Customizing Your Crochet Cat Alien
One of the greatest joys of amigurumi is how easily a base pattern can be transformed into something completely unique. Here are a few ideas to make your crochet cat alien plush toy your own:
Different colorways completely change the character’s feel. A dark navy blue cat alien with silver antenna reads as a mysterious nighttime creature. A pastel pink version with holographic yarn accents feels sweet and dreamy. A bright acid green with mismatched eye colors screams eccentric alien scientist.
Clothing is another fun option. A tiny crocheted spacesuit, a felt cape, or even a simple knitted scarf can take your cat alien from naked plush to fully accessorized character.
Size variations are easy to achieve by changing your yarn weight and hook size. Use bulky yarn for a jumbo pillow version, or use fingering weight yarn and a 1.5mm hook for a miniature keychain version.
You can also add wings using a simple flat oval pattern worked in a sparkly or gradient yarn, turning your cat alien into a cosmic flyer.
Tips for Making Your Amigurumi Look Polished
Even with a well-written pattern, a few technique tips can make the difference between a good amigurumi and a great one.
Consistent tension throughout your work is everything. If your tension varies, some parts of your piece will be looser and allow stuffing to show through or create uneven shapes. Try to maintain steady yarn tension from round to round.
Always close your magic ring tightly before working your first round. A loose center creates a visible hole that’s hard to fix later.
Stuff firmly but not so tightly that the piece becomes rock-hard. The goal is a firm but slightly squeezable plush.
When sewing pieces together, going around the attachment point twice gives a much more secure bond. This is especially important for parts like the head, which bears weight, and the ears, which get grabbed by small hands.
Weaving in your ends securely is the final step that separates a lasting amigurumi from one that starts unraveling after a few months. Weave through at least five or six stitches, reverse directions, and weave through a few more before trimming.
Making Multiple Cat Aliens for Gifting or Selling
This crochet cat alien plush toy amigurumi pattern is ideal for batch production because the individual pieces are small and quick to work up. Many crocheters find an assembly-line approach works best — crochet all the heads in one sitting, then all the bodies, then all the small pieces, before moving on to assembly day.
If you’re selling your finished cat alien plushies, this pattern makes for a wonderful product since the design is distinctive, photogenic, and appeals to a wide range of buyers including children, cat lovers, sci-fi fans, and anyone with a soft spot for unusual, creative plush toys. Make sure to present them in good lighting against a simple background when photographing for online shops, and consider offering custom colorways to increase appeal.
Final Thoughts
There’s something genuinely magical about holding a finished amigurumi in your hands. You started with a ball of yarn and a hook, worked round after round, and ended up with a little creature that seems to have its own personality. This crochet cat alien plush toy amigurumi pattern gives you a project that’s creative, satisfying, and results in something truly special — a tiny cosmic cat that’s ready to explore new worlds or just sit on a shelf and be adored.
Whether this is your first amigurumi or your hundredth, take your time, enjoy the process, and don’t be afraid to make the pattern your own. The universe of crochet is big enough for every kind of cat alien you can imagine.
