#1 Sad Marshmallow

Is that a marshmallow, or a cat? Either way, it's an adorable kitten and we just hate to see it looking so depressed! Perhaps this cat is trying to become the next famous Grumpy Cat?

#2 Party Like It's 1990

It's this cat's party and he'll cry if he wants to...It looks as though someone reminded this cat that the good old days are well and truly over. It was 1990 twenty years ago after all!

#3 Disappointed Cat

This feline in Japan has been named 'Disappointed Cat', following in the footsteps of the world-famous 'Grumpy Cat'. His heavy-set brow causes him to look constantly sad and disappointed - Poor thing!

#4 Has A Sad

This super sad cat is 'having a sad', and it makes us just want to rush over and give it a big hug! Seriously, where are the owners of these depressed kitties? Behind the camera lens most likely...

#5 Seen A Ghost

This cat looks as though she's seen a ghost! Perhaps that is why she is so upset? Either way though, we think this kitty is extremely cute - Just take a look at those tiny ears!

#6 High Expectations

This standing kitten makes our heart burst every time we look at it! Have you ever seen such a solemn-looking little thing? This cat looks as though his expectations have not been met, and as a result, he sure is upset.

#7 Is Very Sad

Sad cat is very sad indeed! We're not quite sure what happened to make this kitten so upset, but we're sure with a dose of sunshine she'll be feeling better in no time!

#8 Given Up

This poor feline looks as though she's just given up on everything! There's something about that squished in nose and round eyes that makes her look so extremely sad...Cheer up girl!

#9 Newborn Problems

We've all heard of First World Problems, but this little kitten is having Newborn Problems! At such a young age, this kitty is already saddened by what he sees. Is the world really that bad? Someone give this guy a bottle of milk!

#10 Boxed In

No wonder this cat looks so forlorn...she's stuck inside a box and is too small to get out! Perhaps she's suffering from claustrophobia, or is just too disappointed in her owner's antics to even crack a smile?

#11 Cat On The Mat

The cat sat on the mat...and hated every second of it. We can think of many reasons as to why this cat doesn't look too impressed. Firstly, she's got a cone around her neck from an injury, and secondly, she's wearing a onesie! Does it get any more embarrassing than that?

#12 Pensive

This little kitten sure does look pensive, but we wonder what deep thoughts are crossing his mind? Perhaps his dinner is a little later than usual? Somebody feed this cat immediately!

#13 Summertime Sadness

When the weather is warm, that can only mean one thing...Bath time! This kitten (much like Lana Del Rey) has got that summertime sadness. She looks a bit like a drowned rat, and she certainly isn't happy about it.

#14 Put Me Down

Well, if it isn't the original angry and depressed cat - Grump Cat! Even poor old Grumpy Cat can't get into the Christmas spirit...That's just how much he hates the world!

#15 Broked Hearts

If there's one thing this cat is sad about, it's probably her poor grammar. Regardless of this though, her heart is still "broked". Poor little thing! We think she needs a cat nap to cheer up...

#16 Feeling Blue

This poor cat is so blue that his eyes have turned the same shade! This kitten might look sad, but he sure is adorable...Can we keep him?

#17 Maybe Another Time

We've all felt like this cat at one time or another - disappointed and feeling rejected. Naww! Maybe it's time that this cat found some new friends, preferably not dogs!

#18 So Many Potatoes

It's Mr Potato Head, but in kitten form! At least we actually know the source of this feline's worries - Too may potatoes of course...We think it's time that this kitten changed its' diet.

#19 Waiting

This cat is more than a little sad...He's been waiting for how owners to get home from work for hours now! They say dogs are a man's best friend, but trust us, cats can be just as loyal!

#20 Shower Time

Have you ever seen a cat look so stressed, frightened and sad? It's obvious that this cat doesn't like showers, especially when they're with its' naked owner! The look of sheer desperation on this cat's face is a little funny though..."Please, save me!"

#21 Fear-Cat

Put this poor cat with a few meerkats and he won't be happy! The anxiety on this poor feline's face makes him more like a 'fearcat', rather than a meerkat...Get this cat out of the zoo!

#22 Turns To Vodka

Sad cat is sad, so he turns to vodka. We don't blame him though - It looks like he's lost his feline lover to a DOG! Someone might need to get this cat to rehab, and ASAP!

#23 Sadness On Toast

We have to admit, getting our head caught in a slice of bread would probably make us a little sad too. It's hard to smile when you look like you're on the receiving end of a bad joke!

#24 Sad Cat Feels Nothing

You know your cat is sad when he wishes he was Grumpy Cat because at least Grumpy Cat "feels something". Come on kitty, cheer up! Surely your life ain't that bad?

#25 The Ultimate Sad Cat

We've left the saddest cat for last - it's Puss In Boots of course! It's pretty hard to beat those adorable eyes and that little frown...Just remember though, all cats are incredibly smart, and they may just have an ulterior motive in mind!
