Slip It On and Your Cat Becomes the Most Intimidating Thing in the Room

These cat muscle arms are a 3D printed photo prop that slips over the neck like a collar. The oversized arms hang at the sides and swing as she walks, which is what sells the illusion, and the whole thing weighs almost nothing. It is a prop for a photo session, not something to leave on.

Where It Actually Gets Used

  • Photo sessions and short videos for social media
  • Halloween, cosplay and birthday photos
  • Small dogs too, not only cats
  • A gift that costs less than a card and gets a bigger reaction
  • No clips or buckles, the loop just goes over the head

Light Enough That She Still Moves Normally

The arms are printed in PLA, which the maker describes as non-toxic and pet-safe, and they are hollow rather than solid, so there is no heavy bulk hanging off her neck. She can leap, lounge and play in them, which is the difference between a prop you get one photo out of and one she tolerates long enough to get a good one.

Six Colors, One Very Silly Idea

Green, yellow, skin color, gray, black and white. Skin color reads most like real arms in a photo, black and white are the ones that show up best against a light or dark coat, and the bright colors are the ones that read at thumbnail size on a phone.

Safety Note

This is a photo prop, not everyday wear. Stay with your pet the whole time it is on, take it off as soon as she looks uncomfortable or tries to back out of it, and never leave her alone or let her jump onto high shelves while wearing it.

Get the Photo, Then Take It Off

Two minutes of flexing is all it takes, and you will be using that picture for years.
