Your cat will go crazy for this DIY catnip-filled mouse cat toy. It's an easy hand sewing project in which you can compete in about an hour. Grab the free pattern and start making something fun to give to your cat.

Cats don't rely on realism for their toys, so you can use colorful felt to make this little mouse. But of course, you can use any colors you like! Just be sure to use quality felt so the toy lasts longer and stays safe for your kitty.

This is designed for hand sewing, making it a good project for kids to practice their sewing skills. But it's also possible to make with a sewing machine if you prefer.

Cut the Toy Pieces

Follow the pattern templates to cut out two side pieces, two ears, one bottom piece, and one tail from the felt.

Cut all the pieces from one color of felt for a monochrome mouse or use several colors to make it look more realistic. 

Attach the Mouse Ears

Fold and Sew the Ears to the Sides

Fold the narrow end of an ear over and hold it near the pointed nose end of a side piece. Stitch a vertical line across the fold. Use three strands of embroidery floss and backstitch to secure the ear.

Repeat this on the other side piece in the same location so that both sides match.

Sew the Sides of the Toy Together

Hold the two sides with the wrong sides facing each other. Starting at the nose end, sew across the back with three strands of embroidery floss using a running stitch. When you get close to the end, sandwich the large end of the tail between the layers and continue stitching to the end of the back.

Stitch across the back again with running stitch, this time filling in all of the gaps. The result is a strong and attractive line of hand sewing that resembles machine sewing.

Attach the Bottom of the Mouse

Place the bottom piece in the open underside of the mouse shape. Fold the shape in half to find the center point of the wider back and then match the front point with the nose of the mouse. Use pins or sewing clips to hold the piece in place as you stitch.

Sew with three strands of embroidery floss and use a running stitch as before. Start at the nose and work toward the back on one side. Stitch back toward the nose, filling in the gaps. 

Start stitching along the bottom on the other side. Stop about one inch from the tail end of the mouse.

Fill the Toy With Stuffing and Catnip

Add a small amount of stuffing inside the mouse, and then add about one teaspoon of dried catnip. Finish filling the toy with more stuffing.

If you want to skip the catnip, you can add a bell or some crinkly cellophane inside instead.

Finish sewing the bottom seam with a running stitch and then go back and fill in the running stitches, working toward the nose end.

Secure the thread with a strong knot hidden between the layers of felt.

Finish and Make a Mischief of Mice

Your first mouse is ready for play. But since your cat will undoubtedly go crazy for this toy, you might want to sew up a whole mischief of mice! You could even sew a few extras to donate to an animal shelter.

As with all pet toys, it's important to watch how these catnip mice wear with use. If you see an ear or tail coming loose, remove it entirely. If your cat tears a hole in the felt, discard the toy so they don't ingest any stuffing.
