Crochet Cat Cave with Reinforced Oval Base – Free Pattern

This original crochet cat cave pattern explains how to make crochet cat cave with reinforced oval base from the first counted stitch through final assembly. The design is a practical free tutorial in US terms, with measurements and stitch checkpoints that you can verify as you work.

The foundation makes a full oval rather than a flat rectangle. Nine marked increase rounds expand both ends while the straight sides remain constant. Eight joined wall rounds rise from the back loops. The final upper shell is worked in turned rows over the back of the opening, decreasing at each end before the top is seamed.

Pattern Details

• Hook Size: 8 mm with two strands of bulky cotton blend held together; adjust to a firm fabric
• Finished Size: Planning footprint about 21 × 14 inches; lower wall about 4.5 inches; front entrance about 10 inches wide and 10–12 inches tall; size varies strongly with washed gauge
• Gauge: 7 sc and 7 joined rounds or turned rows = 4 inches after washing while holding two strands together
• Estimated Time: 14–20 hours
• Construction: 32-stitch oval foundation increased to 104, eight 104-stitch wall rounds, 18-stitch front opening, fifteen tapered upper rows and a 29-pair top seam
• Skill level: Intermediate

Why You’ll Love This Project

The shape comes from counted stitches rather than an unexplained diagram. You can inspect each stage against the measurements, and the finished object has a clear purpose and a distinct silhouette in photographs.

Materials

• Approximately 1,000–1,250 yards of washable bulky cotton-blend yarn in oat, held double throughout; 60 yards olive for the edge and pad trim
• 8 mm hook, at least 10 locking markers, large blunt needle, tape measure, scissors and a removable washable flat pet pad cut to fit inside the finished base

Gauge, Measurements, and Planning

The two-strand fabric must support its own weight when the opening is held open. Make a 7-stitch by 7-row washed swatch and leave it standing against a wall for ten minutes. If it flops, use a smaller hook or firmer yarn. At the target gauge, the 12 straight stitches along each side contribute about 7 inches; the rounded ends add the rest of the approximately 21-inch length. Measure the actual oval after Round 10 before starting walls. This medium-cat plan may need resizing for a larger cat.

Make and wash a gauge swatch before beginning. Measure only after the swatch is completely dry. If the stitch width differs, change hook size rather than pulling the working yarn tighter. Keep a written count at the end of every section so the finished edges remain balanced and the assembly points line up.

Abbreviations and Special Stitches

• ch: chain
• sc: single crochet
• sl st: slip stitch
• st(s): stitch(es)
• rnd: round
• inc: 2 sc in one stitch
• sc2tog: single crochet two stitches together

Special stitch guidance: The oval start is divided into two straight segments of 12 sc and two marked end arcs of 4 sc. On each following base round, increase four times on each end arc while working one sc in each of the 24 straight-side stitches. For the dome, skip 18 contiguous front wall stitches and work across the other 86, then decrease at both row ends.

Important Notes

• AI-generated pictures illustrate the intended design; they are not photographs of a physically tested sample. Follow written counts rather than counting stitches in an image.
• The stitch arithmetic has been checked, but gauge, yardage and fit are planning targets until a physical sample is made. Wash a swatch and check measurements before gifting or wearing.
• A beginning ch 1 and a joining sl st never count as a stitch in this pattern. Mark the first counted stitch of each row or round.
• If a row count is wrong, return to that row. Adding an unplanned stitch later changes the shaping and the assembly alignment.

Complete Instructions for Crochet Cat Cave with Reinforced Oval Base

Crochet the Reinforced Oval Floor

Use two strands together. Mark the first sc, the four stitches on each rounded end, and the boundaries between each end arc and its neighboring straight side. Joined slips and ch 1 lifts are excluded from counts; do not turn the oval rounds.

1. Base Round 1: Ch 15. Starting in the second chain from the hook, sc in the next 12 chains. Work 4 sc in the far end chain. Rotate to the unworked underside of the foundation, sc in the next 12 opposite chain loops, then 4 sc in the near end chain. Join to the first sc. (32 sts)
2. Base Round 2: Ch 1, sc in each of the 12 straight-side stitches, 2 sc in each of the four far-end stitches, sc in each of the other 12 straight stitches, and 2 sc in each of four near-end stitches. Join. (40 sts)
3. Base Rounds 3–10: Keep the two 12-stitch straight sections unchanged. On each end arc, repeat [sc in next k stitches, 2 sc in next stitch] four times, using k = 1 in Round 3, 2 in Round 4, through 8 in Round 10. Each round adds four stitches at each end, eight total. Keep the four increases evenly spaced within each arc.
4. The complete oval count chart is Rnd 1 (32 sts), Rnd 2 (40 sts), Rnd 3 (48 sts), Rnd 4 (56 sts), Rnd 5 (64 sts), Rnd 6 (72 sts), Rnd 7 (80 sts), Rnd 8 (88 sts), Rnd 9 (96 sts), Rnd 10 (104 sts). After Round 10, there are 12 straight stitches on each long side and 40 stitches in each rounded end arc. If the oval waves, recheck the eight increases per round rather than omitting a random stitch.

Raise the Dense Lower Wall

The back-loop transition gives the wall a clean hinge. Mark a continuous 18-stitch stretch at the middle of one long front edge for the future entrance.

1. Wall Round 1: Ch 1, working in back loops only, sc in each of the 104 base stitches and join to the first sc. (104 sts)
2. Wall Rounds 2–8: Ch 1, sc through both loops in every stitch and join. Do not turn. Check (104 sts) after every round; the wall is approximately 4.5 inches high at the target gauge.
3. Lay the bowl-shaped lower section on the floor. It should sit flat on the full oval, without a curled lip or a pulled-in end. Mark 18 contiguous stitches centered along the front long side; place one marker on each side of that span.
4. If the base and wall sag before a cat enters, stop here and change to a firmer yarn or smaller hook. A soft, collapsing shell cannot be repaired by adding a rigid loose insert later.

Shape the Front Arch and Tapered Dome

The 18 front stitches are left unworked for the opening. Work the upper shell back and forth over the other 86 stitches and turn at the end of every row.

1. Dome Row 1: Join yarn at the marker immediately after the 18 front stitches. Ch 1, sc in each of the other 86 wall stitches until reaching the front opening marker; leave the 18 front stitches unworked, then turn. (86 sts)
2. Dome Row 2: Ch 1, sc2tog over the first two stitches, sc in each middle stitch, sc2tog over the last two stitches and turn. (84 sts)
3. Repeat the same paired edge decrease on every row through Dome Row 15, turning after Rows 2–14. This creates an increasingly narrow upper shell while the two sloping edges frame a broad open arch. The row chart is: Row 1 (86 sts), Row 2 (84 sts), Row 3 (82 sts), Row 4 (80 sts), Row 5 (78 sts), Row 6 (76 sts), Row 7 (74 sts), Row 8 (72 sts), Row 9 (70 sts), Row 10 (68 sts), Row 11 (66 sts), Row 12 (64 sts), Row 13 (62 sts), Row 14 (60 sts), Row 15 (58 sts).
4. At the end of Dome Row 15, do not fasten off until the top seam is checked. Fold the final 58-stitch edge with right sides facing, align the first stitch to the last, the second to the next-to-last, and so on. Sew through all 29 aligned pairs to close the crown; turn right side out.
5. Join olive at the lower left entrance corner and work one firm sc in each visible row end along the left arch, across the 18 unworked front stitches and down the right arch. Do not pull this edge so tightly that the opening narrows. Fasten off and weave in ends away from the entrance.

Make and Place the Washable Pad

The removable pad is independent of the shell so the inside can be cleaned and inspected. It must lie flat without a loose cord or attached toy.

1. Use the actual dry base as a template to cut a washable flat pet pad about half an inch smaller on every side. Cover any raw edge with a stitched washable binding; do not use buttons, loose loops or stuffing that can escape.
2. Lay the pad on the floor inside the finished cave. It should lift out in one piece and leave the 18-stitch entrance completely unobstructed.
3. Place the cave on a non-slip level surface. Press lightly on the top and release: the entrance should spring back open. Inspect yarn for chewing and wash the pad and shell according to their separate care labels.

Assembly and Shaping

The oval floor and wall form one continuous crocheted shell. The front 18 stitches remain at wall height while the 86 back stitches rise as 15 turned dome rows; the final 58 stitches fold into a 29-pair top seam. Shape the entrance edge without closing or bridging the arch. The independent pad sits flat inside and is removed for cleaning.

Lay every component on a flat surface before joining. Match the marked centers first, then divide each remaining edge into equal sections. Work through both layers with consistent tension and pause after each section to check that the fabric lies flat. This measured approach prevents twisting and keeps decorative details facing the intended direction.

Finishing

1. Weave each tail along three different paths on the wrong side; reverse direction before trimming.
2. Wash or damp-block according to the yarn label and allow the work to dry at its measured shape.
3. Inspect every seam, edge and attachment from both faces before first use, then inspect again after laundering.

For a polished result, weave each tail through several same-color stitches, reverse direction once, and trim only after the fabric has been gently stretched. Block to the listed dimensions without flattening textured stitches. Inspect joins, borders, straps, and decorative pieces before the project is used or gifted.

Helpful Tips

• Use contrasting locking markers at shaping points and record the count after every change row.
• Change hook size when the washed swatch differs from the stated gauge; do not compensate with uneven hand tension.
• Photograph the flat components before joining so it is easy to identify an inverted or twisted piece.

Good lighting and a contrasting stitch marker make counting much easier. If a section looks uneven, compare the current count with the previous checkpoint before continuing. Fixing one missed stitch early is faster than compensating later, and it preserves the measurements used by the assembly instructions.

Frequently Asked Questions

Will the cave stand without wire?

It should if the doubled yarn and washed gauge yield a firm fabric. Check the shell before pet use; change yarn or hook if it collapses rather than inserting loose wire.

Can a larger cat use this size?

Measure the cat’s relaxed body and compare it with the actual blocked floor and entrance. Do not rely on the planning dimensions if your yarn or gauge differs.

Conclusion

The completed cat hideaway has a counted oval foundation, a stable lower wall and a shaped open arch. The removable pad makes care easier, while repeated stability and wear checks help keep the space suitable for a pet.
