This was originally were something like a illustration for a head-canon I wanna work on. But I found the picture amusing, so I just went and drew it just as a seperate drawing.
 
I also add what I have at the moment of that head-canon here (at least the things that relevent to this drawing).
 
No idea when the whole thing will be done, probs going to be for a while.
 

 
“What diffentiate a creature from an animal?
 
Short answer: A certian level of intelligence.
 
Long answer: Every creature has different levels of magic. Certian creature can tap into this magic and use it (like unicorn ponies). Some creatures have high levels of magic, like the ponies. Unicorns are already mentioned, but this inner magic helps pegasi fly and gives earth ponies their strenght. This is also what’s behind ponies’ cutie mark.
 
Creatures, like for example zebras, donkeys and cows, also has this magic but on a much lower level. The only effect this has on their bodies that they able to use advenced languages (like ponies’s Ponish) and they not controled by animal like instincks.
 
So in short, if someone able to speak and not, let say “wild”, they are creatures.
 
So that means there could be a creature and animal who seems to be the same spieces. This is how the deers of the Ticket are creatures, but there deers that are animals.
 
So that also mean, somewhere in the world there are horse and pony animals.”
 

 
“There are creature that live a so called ‘free-roam’ life style (for example cows and sheeps). This means they spend their days and nights outside in nature and get everything they need form there.
 
This life style slowly started to fade a little of the centauries. Lot of them, similary to ponies, live in houses, work at places, basically have a more ‘modern’ life style. Most those are mainly live outside of Equestria or on the border of it. There some in the kingdom, but most still live free-roamly or in a new life style called ‘housing’.
 
This life style born mainly, because of how their relationship with ponies formed. Some of them ended up “working” partially for ponies. Which meant they give things only they can provide (cows their milk, sheep their wool), in exchange for some other goods or/and, as the name suggest, for some form of housing. This symbiotic relationship formed centauries ago and still goes today. For some of this creatures this is the norm what they used, even tho they could freely start leaving next to ponies (as is already seen with donkeys). Lot of this creatures outside of Equestria found this life style weird.”
 

 
For example here, while the Apple family main export is, well, apples, they sell a some amount of things like wool and milk or use it for themselfs. They pretty much have been doing ever since Ponyville was built. But they not really doing it for themselfs. While they take some of the, for example, wool as payment for letting the sheep sleep in the barn and exchange for apples, most of the wool is sold and goes back to the sheeps. They also do it, to help out the sheep with the crazy amount of sheering which they need to do from time to time.
 
So yeah, it’s not really a working relationship, here Sean calls Applejack boss mostly for the heck of it.
 
By the way, the Apple farm also has pigs, however, they don’t have any level of magic, making them animals. They keep them for mushroom farming.
