Nobody really knows what caused there to be a size difference between macros and micros. One thing we know is that it didn't always used to be like this. There were no over-sized plants and vegetation that destroyed houses with their roots and vines, there were no insects that could grow to the size of a compact car, and there were definitely no macro furies that delighted in hunted down and swallowing their smaller cousins whole. This, however, was all before the rise of the macros. As you can imagine, there was a great deal of confusion when one day regular furries, animals, and plants rapidly began to grow to many times their original size. At first, there seemed to be at least some form of cooperation between the two groups as they tried to repair the damage that had been done. However, macros soon started to give up on the idea that the two groups could ever be considered equal. This was largely due to the fact that an average adult-sized micro was only about an inch tall when compared to one of the massive giants. Micros were crushed beneath the macro's paw pads without a second glance (sometimes intentionally) as the giants trudged about their daily lives. By this point, micro's live's were thought of by most giants as entirely insignificant. Micros were snatched up from their homes and devoured, not because they were the only source of food for the macros or even remotely as filling as some of the macro's other options, but simply because they were powerless to stop them. The fact that the macros only needed to eat once or twice a week brought the micros little hope. Even if the macros weren't hungry, they would still find other cruel and unusual things to do with the micros to keep themselves busy. Some micros gathered together and fled to remote locations away from most of the dangers that they faced. This didn't protect them from everything however. No matter where they went, there was always something big that had it's eye on them. Even if there were no macrofurries around, micros found themselves being eaten alive by the animals that had grown on that day as well. It was a dangerous new world if you were a micro. Macros had destroyed almost entirely all civilization as it was known before they had emerged, creating a new world order in the process where micros found themselves close to the bottom of the food chain. The average micro at that stage was lucky to live to see the age of thirty. Several years passed after the rise of the macros, and for the micros, things only became worse. Macros on the other hand had used that time to build the beginnings of fully macro-sized towns and cities where they could live normal lives again. Things started to look almost identical to how they had appeared before. If you had gone to sleep as a micro back then, and woken up as a macro today, you would notice very little difference at all other than what you ate. Selling micros as food had become a very profitable business venture. Macros ordered micro platters at restaurants and took their time throwing the little ones into their mouths and crunching down on them. The giants could order anything from stir fried micros to ordinary live micros, which was most common. Another profitable venture was selling micros in packs as aphrodisiacs or masturbation enhancers. For most macros, the sensation of a dozen little bodies squirming against their loins was well worth the effort of going out and finding their own micros or buying packs from the store. Most macros bought pre-packed micros to avoid the hassle of having to collect their own and de-claw and tooth them. The companies that sold these packs, along with other things, did all of the prep work before hand including removing the micros clothes which made things a whole lot easier for the horny giants. As years went by, this relationship between macros and micros continued to exist. The macro's population increased substantially and so did the micro's despite their circumstances. Both groups became accustomed to their rolls as predator and prey; master and pet; and as an individual and his or her property. A macro entered in his kitchen, he was an enormous and beefy heavily muscled grey bull. This bull was looking to be in his twenties and his exaggeratedly massive muscles rippled with each of his movement. He sat on a chair in front of a table and started to toy with a wiggling tiny form held between two of his humongous fingers. That form was a grey furred anthropomorphic cheetah, slim and muscular and visibly older than the bull. The young bull was visibly delighted by his improvised tiny plaything and took great pleasure to rub the sole of the feet of the cheetah with the tip of one of his enormous fingers. The cheetah wiggled and squirmed, unable to escape from the tight grip of the bull's fingers. "Please... let me go," the cheetah pleaded, his tiny voice barely audible to the giant bull. The bull chuckled darkly. "Why would I let such a cute little thing like you go?" he asked, bringing the tiny cheetah up to his face. He grinned as he saw the fear in the micro's eyes. "You're much more fun to play with than any toy I could buy." The cheetah squirmed again, trying desperately to get free from the bull's grasp. But it was no use. He was too small and too weak to do any damage to the much larger bull. The bull continued to toy with the cheetah for a few more minutes before finally getting bored and putting the tiny creature on the table. The cheetah stayed on the table, trembling and scared, while the bull walked away to attend to other things. This was the life of a micro in the world of macros. A life of constant fear and danger, where their only purpose was to be a plaything or a meal for their giant masters. The next day the bull went to college and he brought the cheetah in a little cage he put in his backpack. The giant bull was studying the feline anatomy and their suppleness in particular. The section of the college building he went was specialized in scientific studies about micro predators and had a whole wings dedicated to keeping and husbandry of several specimens, a true collection of several micros were kept in cages and the bull could have access to several living feline specimen for his studies. The cheetah was his own possession though, as he was a rare specimen of Acinonyx pardinensis he collected during an expedition in a mountain range. In one of the labs of the college he placed the cheetah immobilized on the mat of a science bench. Several rubber tipped pincers were holding the micro in a position displaying his natural feline suppleness. At his side were a male lion, more muscular but visibly not as supple. He was immobilized the same way that te cheetah and the bull was comparing there anatomy and abilities, examining them closely with a magnifying glass and using a rubber tipped tweezers to prob and delicately move their comparatively tiny limbs.

A college professor, a old and massive ram approached the younger bull student. The ram had somthing to ask to the student. "Seems your work is progressing. I'll have something to ask you. It's about the pardinensis cheetah you own. You already know we don't possess any specimen of this specie in our collection." "Yes, it's a very rare specie, I was lucky to find one in that expedition and as lucky to have succeeded to capture him." Replied the beefy bull. "We don't want to take him from you as he is in good hands in your custody. But we would like to examine him and make some samples. Seeds samples would be important, for preservation, you understand, if ever a female specimen got captured one day."

The cheetah heard the conversation from the cage in the bull backpack. He was not pleased at the thought to be manipulated by the ram and the other macros of the college, he was barely accepting the be handled by the humongous bull's meaty hands already. And if he was thinking about the concerns these macros of the college were having about the preservation of his cheetah species he was not enjoying the idea of his seeds being taken and used on a possible captive female of his species to have give birth of captive cubs. But he also heard the enthusiasm in the voice of the young colossal bull student.

Next day, the father of the bull, a macro anthropomorphic white bull as large than his grey furred son and with a massive musclegut came to visit his son. He is a bit older than the cheetah and both of them had known the world before the rise of the macros. The father seized the cheetah between his humongous callous fingers to examine him as he didn't see a feline from a long time. And after a while both the cheetah and the bull started to chat about the bygone world.

That night as the bull was laying on his wide back on his couch with his cheetah on his pecs as he got into the habit to do so, but he fell asleep some moment later. The cheetah decided to explore his humongous muscular body. After all this bull didn't waste time to do the same with him many time from the moment he captured him.

The bull woke up and started to delicately caress the back of the cheetah. The micro feline stretched out under the huge finger tip. And willing to return the favor he lazily petted the massive mass of firm muscle of the meaty pecs he was laying upon. As he was about twenty time smaller than his younger but gigantic captor the cheetah couldn't rub more than a tiny spot of the bull's vast pectoral muscle and the bull could probably not feel it or barely. Feeling disillusioned the cheetah slipped from the underside of the huge bull fingertip and moved on the bulky surface of the giant's pecs muscle. And he stopped abruptly as he saw his comparatively enormous nipple on the lower side of his manly and beefy pecs. Feeling playful, the cheetah started to rub his comparatively tiny hand on the naked skin hoping it to be more sensitive than the thicker one of the top of the meaty pecs. His tiny claws brushed on the naked skin barely denting it but the areola and the knob of flesh reacted and got firmer under his hands as well the humongous muscle twitched ponderously and shook the cheetah who managed to keep his grip.

The bull seized the cheetah delicately between his enormous thumb and forefinger and brought the micro anthropomorphic creature closer of his face. "So you like to tickle me ?" He said. He then used his free hand to carefully seize and immobilize one of the legs of the feline and brushed the tip of his huge thumb under the cat's way smaller sole.

Later in the day, the father of the bull student came to visit him again. The two bull were talking about some serious subjects about the young bull next expedition in one of these remote lands where micro predators withdrew from the macro herbivores when they expended the territories they needed for their enormous needs. The cheetah was in his cage on the coffee table, the young bull let the door of the enclosure open, but the feline preferred to stay into for the moment. He watched the two gigantic anthros as they were talking, their voice rumbling like thunder. Seeing these two horned and muscular giants among the immense building sized pieces of furniture of the bull's home reminded him these moments of the rise of the macros when the herbivores got gigantic and towered above the buildings of the city he was living at this moment.
