Cat Sweater Knitting Pattern PDF | Easy Pet Sweater Pattern XS–L

Knit a cozy, relaxed-fit sweater for your cat with this Cat Sweater Knitting Pattern PDF.

This simple pet sweater is worked flat in one piece, making it a great option for knitters who prefer not to knit in the round. Two front-leg openings are created on the same row, and the finished piece is folded and joined with a single underside seam.

Designed in 4 sizes from XS through L, the pattern includes detailed measurements, stitch-count checkpoints, fit guidance, and adjustment instructions to help you create a comfortable handmade sweater for your cat.

Beginner-Friendly Construction

This sweater is designed to keep the construction approachable.

Instead of knitting a small garment in the round, you will knit a flat stockinette panel from the lower body toward the neck.

The pattern then guides you through creating both front-leg openings on the same row, restoring the original stitch count, adding the ribbed neckband, and sewing one underside seam to complete the sweater.

Adjustable Fit

Cats vary greatly in body length and proportion, so the pattern includes instructions for adjusting:

• Lower-body length
• Upper-body length
• Front-leg opening size

The pattern also explains how to keep both leg openings centered and symmetrical when making size adjustments.

Designed With Cat Comfort in Mind

The finished sweater is designed so that:

• Each front leg has its own opening
• The lower edge stays clear of the hind legs
• The toileting area remains unobstructed
• The underside seam stays near the chest and belly
• The ribbed neck remains comfortable and flexible

The pattern also includes a first-fitting safety checklist to help you evaluate your cat's comfort and movement.
