He's fine. Everything is fine.
Grumpy black cat. Dripping knife. Absolute zero remorse. This is the Halloween metal sign for cat owners who know exactly what their cat is thinking and have made peace with it. Plasma-cut from 18-gauge steel with the kind of deadpan energy that makes people laugh out loud the moment they see it on your wall.
Works at Halloween. Works year-round. The cat doesn't care either way.

📐 Size Guide & Details
📐 Size Guide & Details
Choose a size that makes the design stand out. For most walls, garages, patios and gift displays, the 24" size is the best everyday choice. If you want a true focal point, choose 30" or 36" for a larger statement piece with stronger visibility from across the room or driveway.
Quick size tip: If the sign will be viewed from several feet away, choose 24" or larger. Larger sizes show off the design better and create a more finished, premium look.
Size Options
Sizes are based on the widest dimension. When in doubt, size up. Larger signs usually look better on open walls and outdoor spaces.
| Size | Best for | Recommendation |
|---|---|---|
| 12" Small | Shelves, small accents, compact spaces | Best for small gifts or tight areas |
| 14" Medium | Entryways, bathrooms, small rooms | Good for smaller indoor walls |
| 18" Large | Bedrooms, offices, hallways | A solid upgrade for better visibility |
|
24" Extra Large Most Popular |
Living rooms, garages, patios, above furniture | Best balance of size, impact and value |
| 30" Jumbo | Large walls, garages, barns, workshops | Great for a bold focal point |
| 36" Mega | Outdoor walls, shops, barns, statement displays | Maximum impact and visibility |
Color Options

Very nice sign with intricate details. Go larger than you would think if you want a sign like the one pictured.
Perfect gift for Father in Law
Purchased the hummingbird metal art sign and hung it immediately in the garden. I’ve been working on this area all summer and this was the cherry on top!
