8 CSS and JavaScript Code Snippets Celebrating Our Feline Friends


The internet without cats would be like an ocean without fish (which cats happen to love). The psychology behind this feline obsession must be fascinating. Perhaps it’s that silly, self-assured behavior that makes humans record every move our pets make.

Whether it’s memes, videos or amusing anecdotes, cats seem to be a subject that brings people together. It’s something that the world needs right now – perhaps more than ever.

Therefore, it’s only natural that cat-related shenanigans spill over into the world of design and code. If you want to create something cool with CSS or JavaScript, why not include your favorite pet? It goes together like kittens and balls of yarn.

If you’re reading this, it’s likely that you have at least some level of interest in this important subject. With that, we’ve done the very difficult work of finding code snippets worthy of these crazy creatures. Enjoy!

Hang in There

The sheer determination of a cat hanging onto yarn is inspiring. It was even the subject of a famous poster or two. Here we have a pure CSS animation of a frisky feline joyfully swinging back and forth. If you’re not motivated by this, please do check your pulse.

Cat at Work

Raise your hand if your cat has ever taken a liking to your keyboard. But how many have actually sat at your desk and typed? This neon kitty is just banging away at the keys while jamming to some music. Cuteness and efficiency are the future.

Animated Loading Kitty

Loading animations are everywhere. They add context and let users know that something good is coming their way. But if the goal is to add a little entertainment to the mix, this elongated feline will do the job with lots of LOLs to spare.

Cat Hands

Ever wonder what it would be like to have the quickness of a cat? This interactive set of cat “hands” may be as close as you can get. The orange paws move along with your mouse. Click-and-hold them to bat the letters around. Just don’t try to do this in real life or you might get some strange looks in the pet store.

Grumpy-Like Cat

No, this isn’t the official Grumpy Cat. It’s not even the Grumpy Designer. Still, the frown on this pure (purr?) CSS animation is undeniably sour. The glacial pace of movement is also indicative of a plump friend who conquers the world on their own time.

CSS Grid: Feline Style

Integrating your favorite things into learning can make for a fun experience. It adds that little extra motivation and reason to smile. Perhaps that’s why so many developers have added cats to their code – like this CSS Grid demo.

Not Your Average Kitty

The level of detail within this animated art is spectacular. The liquidlike movement around the eyes, the gentle steam of the exhale, the bold colors. CSS and JavaScript are used to perfection to bring this cat-inspired work to life.

Building the Perfect Cat

Sure, this drag-and-drop cat builder fun to play around with. But it also utilizes a shockingly small amount of code. In fact, there are less than 20 lines of CSS and JavaScript combined. The bulk of the snippet comes from the included SVG images. Now, what will you build?

Celebrating Cats Through Code

Because cats are so universally loved and recognized across cultures, they make a great subject for code demonstrations. No matter where you are in the world, the sight of a feline likely brings a smile.

Most of all, they simply make learning and experimenting fun. They serve as a catalyst for diving into a snippet and seeing what makes it all work.
