Grumpy Cat with a Knife: Small, Sensitive, and Fierce
This tee captures a perfectly balanced mood of cute and dangerous. For those who embrace their inner softie with a sharp edge, it’s a statement piece that sparks conversation. Wear your duality with humor and confidence.
The Design
Front and center, a disgruntled white cat stands clutching a knife with an air of mock menace. It’s encircled by a chaotic yet charming array of symbols: a bright yellow warning triangle with an exclamation mark, a striking red star featuring a lightning bolt, and a stark crossed-out square. Scattered stars and text banners complete the edgy tableau. The design is rendered in a palette of white, black, yellow, green, red, brown, and grey, highlighting the cat’s grumpy expression and the surrounding bold graphics. Prominently displayed text reads, “I AM SMALL AND SENSITIVE BUT ALSO”.
Material & Fit
Crafted from 100% Airlume combed and ringspun cotton, this t-shirt offers a luxuriously soft feel against the skin. Its light weight of 4.2 oz/yd² (142 g/m²) ensures breathable comfort throughout the day. Designed with a modern retail fit, it features side-seamed construction and shoulder taping for optimal shape retention and a flattering silhouette. Pre-shrunk for consistent sizing and finished with durable double-needle hems, this tee also includes a tear-away label for maximum comfort.

Me llegó un poco más tarde de lo pensado. La camiseta es cómoda, y la impresión está bien hecha. El gato con el cuchillo tiene buen detalle, aunque esperaba que fuera un poco más grande en talla.

It’s a fun tee, but the size runs small. The print has some rough edges from shipping. I still enjoy wearing it though; it’s pretty unique.

التيشيرت رائع. القصة مريحة، لكنه أصغر من المتوقع. التصميم لطيف والمطبوعات واضحة. يضيف لمسة مختلفة لملابسي اليومية, حصلت عليه مع توصيل جيد ولكن استغرق يومين إضافيين.
