Lemon-Yellow Flap Hat Crochet Pattern (Cats & Small Dogs)

Yarn Safety Tip: Always make sure to use washable, pet-safe materials (read our yarn care guide).

Looking for an adorable, lightweight, and pet-friendly cat hat crochet design that actually stays on? The Lemon-Yellow Flap Hat is specially engineered for cats, featuring two wide chain-stitch ear bridges that give sensitive pet ears complete freedom of movement without pinching or flattening.

Worked in vibrant citrus yellow and leafy green using two strands held together for plush texture and gentle structure, this 9-round project takes just 1 to 2 evenings to complete. Finished with three playful two-tone tassels, it makes the ultimate photo prop, winter accessory, and handmade gift for animal lovers.

Step-by-Step Written Pattern Instructions

Part 1: The Crown (Rounds 1–5)

Using Yellow yarn (2 strands held together) and your 4.0 mm hook, we build the rounded top of the hat.

Crochet Crown R1-R5 magic ring yellow circle step-by-step — Photos 1–6: Starting the magic ring, placing your marker, and expanding the crown evenly to 30 stitches.

Round 1: Make an adjustable magic ring (MR), work 6 sc into the ring. Pull starting tail firmly to close center. [6 sts]
Round 2: Work 1 inc in every stitch around. [12 sts]
Round 3: (1 sc, inc) × 6 times. [18 sts]
Round 4: (1 sc, inc, 1 sc) × 6 times. [24 sts]
Round 5: (3 sc, inc) × 6 times. [30 sts]

Checkpoint: Confirm you have exactly 30 stitches. Keep the marker in the first stitch. Do not cut your yarn yet!

Part 2: The Ear Openings (Round 6)

This round forms the crucial comfort bridges that allow your pet’s ears to sit totally naturally.

Crochet Ear Openings R6 chain 15 bridges for cat and dog ears — Photos 7–12: Creating the first chain-15 bridge, spanning 8 skipped stitches, and repeating for the second ear slot.

Round 6: Work 1 sc. Chain 15, skip the next 8 stitches, work 1 sc in the following stitch. Work 6 sc. Chain 15, skip the next 8 stitches, work 1 sc in the following stitch. Work 5 sc to complete the round. [44 positions: 14 sc + 30 chs]

Checkpoint: Verify that neither chain-15 bridge is twisted. The 16 skipped stitches sit underneath the openings and will remain open.

Part 3: Shaping & Color Transition (Rounds 7–8)

Here we stabilize the ear arches and transition to our contrasting forest green edge.

Crochet Corner Shaping R7-R8 green border transition — Photos 13–17: Working into individual chains on R7, and introducing the green border on R8 with 3-sc corner flares.

Round 7 (Yellow): Work 8 sc (working into each chain individually as you pass the bridges), 3 sc in the next stitch, 21 sc, 3 sc in the next stitch, 13 sc. [48 sts]

Cut both yellow strands leaving a 5 cm tail. Join Green yarn (2 strands held together) at the start of Round 8:

Round 8 (Green): Work 8 sc, work 1 inc in each of the next 3 stitches (corner flare), 21 sc, work 1 inc in each of the next 3 stitches, 13 sc. [54 sts]

Part 4: Final Border Round & Edge Fasten-Off (Round 9)

Crochet Final Round R9 green border edging — Photos 18–23: Completing Round 9 with 54 even stitches, securing the loop, and keeping edges smooth.

Round 9 (Green): Work 1 sc in each of the 54 stitches around without increases. [54 sts]

Cut both green strands leaving 5 cm tails. Enlarge the final working loop and draw the cut tails through it to lock the stitch neatly. Gently smooth the green edge flat.

Part 5: Hiding Ends & Tassel Fringe Preparation

Hiding yarn ends with 2mm hook and cutting 14cm tassel bundles — Photos 24–29: Weaving yarn tails neatly inside with the 2.0 mm hook, and cutting 36 strands of 14 cm tassel fringe.

Weave In Tails: Using your smaller 2.0 mm hook, guide all loose yellow and green tails through several dense stitches on the wrong side. Trim flush.
Cut Tassel Strands: Cut 18 yellow strands and 18 green strands, each exactly 14 cm long.
Form 3 Bundles: Divide the cut lengths into 3 equal bundles. Each bundle contains 6 yellow strands + 6 green strands (12 strands total). Fold each bundle in half to create 24 loose ends per tassel.

Part 6: Knotting & Trimming the 3 Tassels

Attaching three two-tone tassels to cat flap hat crown and flaps — Photos 30–34: Pulling the folded loops through attachment points, pulling ends through, tightening, and evening out fringe.

Crown Tassel: Insert your 4.0 mm hook from back to front through the center magic ring of the crown. Catch the fold of one bundle, pull a loop through, draw all 24 tails through the loop, and pull firmly into a neat larks-head knot.
Flap Tassels: Repeat the attachment at the outermost shaped tip of each side flap.
Final Trim: Comb the fringe straight with your fingers and trim with scissors for a neat, plush pompom effect!

Finished handmade crochet flap hat worn on cat with clear ear clearance — The completed Lemon-Yellow Flap Hat! Sits comfortably on cats without touching whiskers or flattening ears.

Frequently Asked Questions (FAQ)

Will this crochet hat stay on my cat’s head?

Yes! Unlike flat or cone hats that rest clumsily between the ears, this flap hat incorporates two large 15-chain arches that allow your cat’s natural ears to poke straight through. The gentle crown curvature and soft side tassels provide natural balance without requiring tight chin straps.

How do I adjust this pattern for larger cats or kittens?

For larger cat breeds with wider ear spacing (like Maine Coons, Ragdolls, or British Shorthairs), increase the chain bridge on Round 6 from 15 chains to 18 chains and skip 10 stitches instead of 8. For kittens or petite cats, reduce the bridges to 12 chains.

Can I wash this crochet cat hat in a washing machine?

If made with 100% acrylic or mercerized cotton, hand washing in cool water with mild, pet-safe detergent is recommended to protect the delicate tassel fringe. Lay flat on a clean towel to air dry.
