CatDog Costume
One fine day with a woof and a purr.
CatDog is the iconic conjoined sibling duo from the classic 1990s Nickelodeon animated series. This costume is a nostalgic favorite for couples or best friends who want to coordinate a fun, two-person outfit, though it can also be adapted as a clever solo look. The signature style features a bright yellow body with brown spots, cat ears on one end, and floppy dog ears on the other.

How to put it together
- 1
Lay the yellow bodysuit or t-shirt flat and apply 4 to 5 large, irregular brown spots using fabric paint or felt cutouts on the back and sides.
- 2
If doing a two-person costume, secure the connecting yellow fabric tube to the waistbands of both partners using heavy-duty safety pins or snaps.
- 3
The person playing Cat puts on the pointed cat ears headband and uses face paint to draw a small black nose and thin whiskers.
- 4
The person playing Dog puts on the floppy dog ears headband and wears the red foam nose or paints their nose tip bright red.
- 5
Coordinate your footwear by wearing matching yellow, white, or neutral sneakers to keep the focus on the cartoon body.
- 6
Practice walking in tandem if you are connected, ensuring you have enough slack in the middle fabric to move comfortably.
Makeup & hair
Keep hair simple or tucked back under the headbands. For Cat, use black eyeliner to draw a small triangular nose and three whiskers on each cheek. For Dog, paint the tip of the nose bright red and optionally draw a light brown patch around one eye.

Tips
- If you are connecting two people, use quick-release snaps or Velcro for the connecting tube so you can easily detach for bathroom breaks or driving.
- Keep the connecting tube relatively short (about 2 to 3 feet) to avoid tripping over each other in crowds.
- Wear comfortable sneakers, as coordinating your steps while attached requires good footing.
CatDog costume FAQ
- How do two people walk in a CatDog costume?
- It requires coordination! Walk side-by-side or slightly angled, agreeing on which foot to lead with, and keep the connecting fabric loose enough to allow a natural stride.
- Can I make a solo CatDog costume?
- Yes! Wear the Cat elements on your head and face, and attach a stuffed plush Dog head and front paws to your lower back or waist pointing backward.
- What is the easiest way to connect the two outfits?
- A strip of yellow fabric with elastic waistbands at both ends works best. You can also use a lightweight, collapsible play tunnel covered in yellow fabric.
