Pokeballs are cruel, and unfortunately, common practice in the Pokeworld (most notably in the Hoenn Region as recent MEW polls indicate). Although we do not fully understand the extent of the contours that lay within the pokeball, there are many theories available. "Ideal Environment Theory" suggests in addition to the natural habitat of Pokemon (e.g. fauna, grass, trees, water, etc.), aesthetic amenities are additionally provided inside the pokeball. This theory, however, neglects to explain HOW a pokeball could accommodate a pokemon on a case-to-case basis. For example, there could be idiosyncratic allergies that might prevent one Magickarp from inhabiting a landscape pursuant to the Ideal Environment Theory. Short of a semi-sentient Pokeball, it would be statistically impossible to predict the eggshell nature ("Togepi Efficiency") of one Pokemon from the next. Further, Pokemon of the same type and species are found to have varying characteristics (See Pokemon Ruby, 2002). Ergo, the Pokeball creators would not have been able to create a standard environment capable of accommodating all Pokemon. Even if the Pokeball creator had that ability, it would have financially bankrupted Silph Co. to manufacture such an ambitious product design (not to mention the various tort liability if a Pokemon were to have an allergic reaction inside the Pokeball). It is highly likely Silph Co. would have taken into account the potential claims for negligent infliction of emotional distress and actual damages that would have undeniably resulted from such a faulty product design.
