Ninja training is something that needs to start early, and this little one is already learning the ropes. She hasn’t got the strength or agility of an adult cat just yet, but she’s already showing a lot of potential to develop into a serious ninja with those hanging skills.

Spot the cat! (Hint: check out the curtain) This poor, innocent dog is absent-mindedly sitting around, watching TV or waiting for his owner to take him for a walk. He’s completely oblivious to the cheeky feline watching from the shadows.

Cats love boxes. We don’t really know why, it’s just one of those facts of life like the sky being blue and donuts tasting great. This crafty cat has sneaked inside the box but left a little gap to peek out and keep an eye on things.

Part of being an expert ninja is all about sneaking around in the shadows, climbing into tight spaces, and always taking people by surprise. It looks like this kitty is nailing every aspect, but we hope she can still breathe in there!

This cat is desperate to be a ninja. He’ll stop at nothing, always working hard to hone his skills and become the best he can be. Unfortunately, those bright, blue eyes of his keep giving him away.

Cats are master hunters, able to pounce on mice and birds with amazing accuracy and agility, but why waste time and energy hunting live food when you can just grab a fish on a line like this? What a leap!

One of the most important skills of any ninja is their ability to blend in with the surroundings. This fluffy white cat is playing the part perfectly, hiding beneath the pillow, almost entirely invisible!

Some ninja legends suggest that the greatest ninjas were capable of actual magic, defying the laws of gravity with extraordinary feats like levitation. For this cat, floating in mid-air looks like second nature.

We’re not sure that this cat is going to be winning any prizes for this disguise, but he’s still doing the best job he can. He gets an A+ for effort!

Many cat owners start to worry when the holidays draw near. Cats can completely wreck your Christmas decorations, climbing all over the tree and knocking things over in their quest to ruin the holiday cheer. This one, however, has decided to dive right into the tree and use it as a super hiding spot.

At first glance, someone could easily look at this photo and not even notice that there’s a cat right in the center. The cat probably thinks she’s perfectly hidden, but those pesky, pointy ears are giving her away.

If you’ve ever had a black cat, you’ll know how easy it is for them to suddenly disappear! They can blend into their surroundings so easily, just like this one here as he sits in front of the TV.

Yes, believe it or not there is a cat in this photo. A very skilled ninja feline can be spotted down near the bottom of the image. Need another hint? Check out the packet of paper towels.

This super sneaky cat had the clever idea of hiding among a bunch of other furry friends. He blends in perfectly with these stuffed animals, but he looks quite a lot grumpier than the rest of them.

Don’t ask us how this cat got up there! We have no idea. Maybe he used a crazy ninja grappling hook to get to the top, or maybe he’s capable of flying. Either way, the owners need to check every angle when walking into a room, just in case he’s waiting to pounce on their heads!

We can’t tell if this cat is either a master ninja or just very clumsy. She seems to be balancing just perfectly on all those hangers, but the look on her face makes it seem like she’s gotten stuck and is going to need some help getting down.

How did you even get in there, little kitty? Let’s hope the owners don’t accidentally start playing pool with the cat inside the table. They’ll never get the balls back if they fall down that pocket.

Once again, we can see how hard it can be for cats to completely hide themselves. Even a trio of trained ninjas like these three friends are doing their best to sneakily hide behind the sofa, but their little ears are giving the game away.

This clever cat has chosen the perfect hiding spot. She’s curled up just right to fit the shape of the sink, and her fur matches the surrounding color perfectly too. If only she’d kept her eyes closed, we might never have even noticed her!

Anyone could walk up to these boxes and shelves and not even notice the furry friend sitting down on the bottom left, peeking out into the world. That’s what being a ninja is all about.

This cat has gone beyond the level of a typical ninja. He’s completely defying the laws of the gravity! Not only has he climed all the way up above the door, but he seems to be hanging upside down to see into the next room.

On paper, a big, strong dog like that shouldn’t have any problem taking on a little feline fluffball, but the dog definitely wasn’t prepared for this cat’s crazy ninja kung fu skills.

This is what we call a ‘ninja in training’. This adorable cat is doing her best to learn the art of hiding, but she hasn’t quite mastered the skill just yet. She’ll get there in the end, though. Keep trying, cutie!

Here’s another ninja cat who is still learning the ancient art. He’s chosen a pretty good hiding spot here, but he doesn’t realize how transparent that material really is. Plus, his little paws are poking out at the bottom.

This ninja kitty has found the ultimate hidey hole! Not only are they perfectly hidden from view, they can also reach out and snatch some snacks whenever they like.

This cat actually seems a little scary! Climbing up to the top of the door is one thing, but sitting there in that crazy pose is really going above and beyond the ninja call of duty.

Spider-Cat, Spider-Cat, does whatever a spider can! This amazingly talented cat must have some super sharp claws to be able to climb up the side of a building like that.

Yes, we can see you, little one. It’s not a bad hiding spot, but you should be careful hanging out so close to all those shoes! Someone might step on you.

This cat seems to be practicing pull ups and working on his biceps with this door hanging technique. How’s he going to get down from there? Either way, it’s a great system for dodging the dog.

This sneaky cat is just too cute! Somehow, he found a little hole beneath the kitchen cabinets. When he heard his owner coming, he poked his adorable little head out to see what was going on.

This cat might actually be the greatest ninja master of all! Either that, or he got super lucky with this disguise and doesn’t even realize how good it is. He’s positioned in just the right spot to have his eyes line up with the lady on the box.

These poor disguises wouldn’t quite cut it at the top level of ninja school, but these cats are doing their best! We’re sure they have awesome ninja futures ahead of them.

These two cats might want to consider a career in the army with camouflage like that! Their beautiful orange and black patterns blend perfectly with the tiles and carpet.

Once again, a clever cat has been caught out by his little pointy ears, peeking over the top of the bathtub. Duck down a little further, next time!

Check out the claws on this guy! He’s ready for anything, whether it’s clinging to doors or slashing his way out of a fight. Nobody would ever want to get scratched by this black cat.

This cat seems to have been watching the old Karate Kid movies with a pose like that! She’s training hard in the art of ninjutsu.

The ultimate rule of being a ninja is to avoid detection, by any means necessary. When this cat saw a camera coming out, he knew he only had a brief window in which to hide. He did the best he could, but we still see a little of his face peeking out behind the blanket.

Here’s another martial artist cat, taking the time to do some kung fu training in the great outdoors on a warm, sunny day. Those little fluffy mice toys don’t stand a chance!

Many cats like to walk about on the kitchen counters, even when they know they’re not supposed to. They often get caught, but any owner would find it hard to spot this sneaky cat, hiding up high among the sunflowers.

This fluffy white cat hasn’t quite grasped the concept of being a ninja, but she’s getting there. She’s got a perfect face mask to hide her identity. Now she just needs to get a little better at hiding those bright eyes and all that fluff.

Here’s another amazing cat enjoying a karate training session on a sunny day. He looks like he’s losing control of his legs a little, but trust us, he’s a kung fu master!

This clever cat has doubled up on his disguises to be twice as invisible as his feline friends! His black fur blends perfectly with the laptop beneath him, and that bag covers up the rest of his body. We really can’t see anything wrong with this. He’s a genius.

Being a ninja is all about fancy fighting moves and sneaky stealth techniques, but it’s also about knowing to keep calm and cool under pressure. That’s why this cat is practicing her meditation techniques.

Some cats sit on chairs. Some of them sit by the fireplace. This one sits on the top of the doors. And if you’ve got a problem with that, well, she doesn’t really care.

This little ninja fluffball has been caught in the middle of her latest sneaking mission! She was on a special quest to steal some ham from the kitchen and tried to sneak away in this tight gap to enjoy it. Unfortunately, her owner smelled the ham and found her!

We’ve all heard of Batman. Well, this is Catman. A crime-fighting climber like no other, he’s always waiting in the shadows, ready to pounce on unsuspecting bad guys!

What is it with cats and hanging upside down? They seem to love it. Maybe they just enjoy seeing the world from another angle, or maybe they’re trying to show off with their sneaky hiding spots and unusual acrobatics.

We’re siding with the cat on this one. She definitely wasn’t sharpening her ninja-style claws on that sofa and she definitely didn’t make matters worse by climbing inside. She just found it like that!

Wow! Has someone been keeping this cat locked up indoors all day long or something? It seems absolutely desperate to bust out of this house, leaping up onto the walls and climbing towards the exit.

This cat must have been raised by bats. There’s just no other explanation for this kind of crazy behavior! It must have taken some mad ninja skills to get up there in the first place.

If your cat can do this, you’re in trouble! Cats pretty much only need humans to give them food and water, but this one has already figured out how to climb up onto the fridge and grab herself a cool drink.

Most cats use stairs in the regular way, walking up and down just like their humans. That wasn’t tough enough for this cat, who decided to climb along the banister instead. It’s more fun that way.

This super strong cat reminds us how important it is to never forget leg day! He’s got super strong legs to be holding onto the door like that and supporting his whole body. No ninja mission is too tough for this guy.

The next few photos in our slideshow are the work of a Japanese photographer named Hisakata Hiroyuki. He actually specializes in capturing snaps of kung fu kitties in action!

This cat is striking a menacing pose, leaping into the air, claws outstretched, ready for anything! Nobody will want to mess around with this mean kitty.

Another amazing photo, courtesy of Mr Hiroyuki. He’s captured a hilarious and powerful moment, as this scared-looking cat stretches out its claws, stands up on its hind legs, and gets ready for combat.

What, you didn’t know cats could fly? Well, this one sure can! He’s showing off an advanced ninjutsu technique to his apprentices, who watch on from the surrounding grass.

We really feel like that old “Everybody Was Kung Fu Fighting” song should be playing in the background of these images. These crazy cats are showing off some explosive kicks and unbelievable maneuvers.

Somehow, cats always have a way of looking graceful and elegant, no matter what they’re doing! We’re not sure how they pull it off, but it sure is special to witness.

A ninja needs to be prepared for any eventuality, ready to adapt to his surroundings and situation, whatever the case. This furry feline is clearly learning how to walk using nothing but his front legs, just in case he never needs to.

This cat took her ninja training a little too seriously. She climbed up to the ceiling of her family home, before realizing that she couldn’t get back down! Her owner had to rescue her in the end.

This cat decided to play that old “the floor is lava” game while climbing the stairs. Since she couldn’t touch the floor, she had to climb all the way to the top using nothing but the handrail. The perfect test of her ninja training!

Here’s another cat just practicing some of his favorite ninja moves. A ninja needs to be flexible, after all! You never know when you might need to do a handstand or curl up into a ball while on a sneaking mission.

It’s lucky that the owner spotted this sneaky ninja cat before closing that door. Otherwise, the poor kitty might have gotten squashed.

This cat’s fur is the perfect color to sneak under the sofa without being seen. At least, that’s what she hoped, but she didn’t move fast enough as her owner spotted her little legs slipping through the gap.

This fluffy ninja got caught in the act! It’s a neighborhood cat, spotted climbing over the fence and into someone’s backyard. You can see the shock and surprise in its bright blue eyes.

Ninjas need to be able to blend in and disguise themselves in any situation. That’s why this cat is practicing his “Sit like a human” technique. Soon, we won’t be able to tell the difference between cats and very small, hairy people!

Sneaking around and being a ninja is tiring work, as proven by this sleepy cat, taking a quick nap mid-mission. It’s amazing how she manages to stay balanced on that beam even when she’s sleeping.

This chunky cat proves that even the bigger and heavier felines out there are capable of ninja master status! He’s managed to get up on top of the shower, waiting for his owner to step inside so he can pounce on them and raid the kitchen for treats.

What a clever kitten! She’s hitching a ride on the dog’s back and blending in with his fur perfectly. Nobody can spot her there, not even the dog himself!

This furry feline is a legend among cat ninjas! His skills know no limits, and even in such a wide photo with so much to see, it’s still super hard to spot him! (Hint: He’s on the right side of the image.)

While sneaking into a mansion or creeping around a castle, a ninja needs to be able to slip into tight spaces in order to make a quick getaway or avoid detection. This cat has totally nailed the technique. Now, she just has to get out of there.

Some more amazing ninjutsu techniques are on display in this image, as one sneaky black cat has managed to infiltrate this bookcase in style. She’s almost invisible, but you can just about spot her, if you look hard enough.

This incredible cat isn’t just hanging out on the door frame like some of his ninja buddies, he’s made his way into the air vents of this house, roaming around inside the walls and using his own secret passageways to peek out and see what’s going on in each room.

This clever cat chose the perfect bundle of teddies to sit in. They all look just look him, allowing him to blend in perfectly and enjoy a peaceful cat nap without any interruptions whenever he likes.
