Glow Cat Long-Sleeve Unisex T-Shirt

Size: Unisex S

Shipping and taxes calculated at checkout. Free U.S. shipping on orders over $200.


The same cat that inhabits the Calamityware dinner plates also graces t-shirts. Simple and serene with a steady gaze. Until the lights go off—then the typically calm cat goes on the prowl (ok, she just glows in the dark for a little while).

Printed on Bella+Canvas black long-sleeve t-shirt (100% Airlume combed and ringspun cotton).

Sizes & More Info

The design is printed using a vintage screen printing style which means the graphic will be lightweight and slightly transparent. Then the design is hit again with glow-in-the-dark ink. The ink will sit proudly on top of the fabric but still has a fairly soft hand.

Screenprinted in Pittsburgh, PA, by Commonwealth Press.
Designed by Don Moyer.

Meow wow wow

The shirt is super soft and I love the glow-in-the-dark design. The shirt seems to run a little bit small (as do many Bella+Canvas shirts), so I’d consider sizing up if you’re in between sizes.

Black cats are the best!

I bought this in honor of my best cats, Poncho and Dutchess. Black cats are often overlooked for the stigma associated with them. I found they make the best cats of all. I miss both dearly. As for the shirt, it's a little stretchy which makes it very comfortable. The bold glowing cat really stands out. It will be worn with pride on Halloweens to come.

Love my glowing cat.

I have hesitated to buy the red or olive cat. Just not my colors. This one is purrfect! That said, the tees are Canvas brand. Size up if you are between sizes. We learned this with our bat tees. This brand runs snug.

Cat’s meow

Perfect. Just as pictured. Lots of compliments. I will be wearing a lot. I am solidly a medium in women’s sizes, but wasn’t sure if a unisex medium would be any different. It fits snug but not tight, just how I like.. If you are between an M or a L, maybe err on the larger side.

Love the design

But mine doesn’t glow in the dark - I’ll keep working on it. My granddaughter was disappointed. Regardless it’s a fun t-shirt and I like the soft, comfy fabric.

Love the shirt

Super soft and silly, this shirt is the best. The glow-in-the-dark eyes are just the right touch of sinister fun. It gets great comments every time I wear it.


The recipient loved this unique gift.

Just in the nick of time

I've loved my red short sleeved cat shirt forever. I wore it to death and THEN I bought a new. It was a summer wardrobe staple. This one in black with long sleeves AND a glow-in-the-dark cat just popped up one day. I ordered it immediately. It's fabulous. Fits just the way I like and it's nice and soft. Did I mention it glows in the dark? It glows in the dark. Yahoo!

Love the cat with the "glowing" eyes. It's long sleeve, soft material, and fits me! Was a wee worried about the unisex size. Usually I need a small women's, but ordered the small and it is perfect!
