From babies to mid-teens to all grown up, these animal friendships share everything from blankets, toys, car seats, beds, food, play dates and a lifetime of love.
Life can’t get any better when you grow up with your best friend by your side. Animal friendships are the best friendships.
We have collected some of the best animal friendships that show before and after pictures of animals growing up together. These pictures are either cute, nostalgic, amazing or all of the above!
1) Kasi the Cheetah and Mtani the Labrador
These two have been best friends since the day they met! Kasi was still small and vulnerable when she first laid eyes on Mtani, but after a couple of years, Kasi has now outgrown her loyal friend. Look at the fun these two have together! Kasi The Cheetah: “Hey Mtani, try and catch ‘meow-side!'”
Best friends share the shotgun seat together, forever and always. These two pups have definitely grown a lot since their first picture, but these best friends will never fight for the ‘shotgun’ position in a car – they’ll just hang out there as a team!
3) Foxes and dogs can definitely be friends!
Jupiter the fox and Moose the dog are the real-life fantasy of Disney’s heartbreaking movie, “The Fox and the Hound.” Even though their characters may differ a lot, these couldn’t live without each other. They’ve been best friends for years with still many more years to come!
4) Internet-famous cats
Meet the adorable duo of Izzy and Zoë. With over three hundred thousand followers on Instagram, these two adorable kittens can definitely consider themselves internet celebrities. They’ve been stealing hearts of everyone ever since they were little. Also, take a closer look at Zoë – one of her spots on her chest looks just like a heart!
5) Their names are Oreo and Pumpkin
Can you guess which one is which? This dynamic duo is just something else. Pumpkin the raccoon was rescued after she was found roaming the streets, and a loving family in the Bahamas has decided to adopt her. Now Pumpkin thinks that she’s a dog too and it’s absolutely hilarious.
6) Milo the dog and Stuart the guinea pig
This duo has been inseparable ever since Stuart was a baby. And even though they’re different species, they do a great job at rocking the same hairstyle. Milo and Stuart are a sight to behold together, and Stuart looks glorious with his long locks!
7) Keeva and Peanut
The French bulldog Keeva used to walk with Peanut the pig. Now Peanut walks Keeva. After all these years, the roles have been reversed! Keeva himself isn’t too happy with the change, but he still loves fooling around with Peanut all the time.
8) Floppy friends
Best friends who have ears that flop together, stay together. These two will never leave each other’s side and do just about everything together. The coolest thing about this duo? They’ll flop their ears in unison and it truly makes for a sight to behold.
9) Four lifelong friends
A quadruplet made up of dogs and ducklings are so adorable that it’s beyond words. According to BuzzFeed, the ducklings and dogs love to take naps and strolls together. The dogs keep the ducklings warm and safe from harm. The two pups Pikelet Butterwoll and Patty Cakes Huckleberry simply love taking care of their two duckling friends, even if they’re a little bit larger now.
10) Lili and Renley
These two adorable felines are two peas in a pod. They’re cuddle buddies for life, outgrowing their beds together since their kitten days. These two have been hanging out with each other ever since they met, and they constantly keep insisting on sharing the same place to sleep. Even though they listen to the names Lili and Renley, perhaps a more appropriate name would be Yin and Yang!
11) Fast-forward three years
These two adorable four-footers were named after the Shrek movie, which means they respond to the names ‘Shrek’ and ‘Fiona’. The first picture was taken three years earlier. What a difference just a couple of years can make!
12) Three Musketeers
Just look at these three little goofballs! Even though they’re all grown up now, you can still spot a bit of their mischievous side. Friends then, friends now, friends forever! If the three musketeers had a canine equivalent, this would be the closest thing.
13) Rescued together

16) Tucker and Stewie
There aren’t many things on this planet that are cuter than kittens who are just a couple of weeks old.

And from the looks of it, their playful personality probably hasn’t disappeared too.
17) Not everyone grows a lot
The before and after pictures of these two best buds are hilariously adorable. The little white terrier must be wondering when his growth spurt will sink in. Even though they’re very different in size now, their love for each other has always been the same.
18) Love is timeless

28) It runs in the family
Who knows, maybe animal cuteness is hereditary? Take a look at Monkey and Louve, two close sisters who almost never spent time alone. A fun fact is that Monkey is actually the mom of ‘The Birmans Brothers’ from the previous slide.

No matter what, these two hilarious Staffordshire Bull Terriers will always be ready for a great family photo. These two pets just love dressing up for special occasions, and their love and affection for each other is just simply too cute to witness.
32) Best of friends

33) Always taking care of each other

34) Always in for cuddles
Great Dane puppies are just so adorable – they’re calm and will never say ‘no’ to cuddling with a best friend. From the very beginning, this Great Dane and his new friend got along very nicely. Even though they’re now both similar in size, the cuddles never stopped!
35) A little bit too big
When these two adorable kittens were small, they would both end up sleeping in these beds. Months passed and they’ve definitely outgrown their favorite sleeping places, but they don’t seem to mind at all.
36) Hedgehog fun
A pup and a hedgehog – those two animal species would never get along, right? Think again. Meet Biddy the Hedgehog and his adorable sister Charlie. Wherever they go, the duo has wild adventures together and they’re always enjoying each other’s warm company.
37) Always sleeping in the same spot
They say that it’s pretty hard to break a habit, and that’s precisely what these two are able to illustrate. The two labradors always share the couch together, although one of them usually ends up sleeping on its friend’s butt. Ah well, as long as they’re comfortable, right?
38) Size switch
Talk about a switch in sizes! Zena is the English Springer Spaniel, and she has always gladly taken care of the adorable Boxer named King. But as you can see, King is clearly the bigger pup of the two now. What matters most is that Zena and King always have been and always will be the best of friends.
When the ginger kitten Minnie first met his older sibling Evin, he immediately knew that they’d be best of friends. Apparently, the two felines hit it off really well. We can only imagine the amount of joy these two similar and playful cats bring into the house.
40) Belle and Blue
It’s just amazing how much a small pup can grow in a small timeframe. Belle – pictured on the left – has apparently grown both in body and attitude, according to her owner. The two pups are fantastic friends, and even though Blue does seem a bit restless, it’s because he doesn’t like to pose for the camera.
Time really flies, and these 35+ amazing pictures are perfect examples of that. Seeing animals and their friendships evolve over the years is definitely something that’ll instantly put a smile on your face.
