A "Spark" is documented as the effect on the magically artificial landscape of the valley's haven on the mind and body of the feline inhabitants. A Spark, however, manifests in a visible way amongst only a few cats. It is commonly a minor, yet still unique change in the physical appearence of the cat, alongside an increase in (or the development of) a certain trait/ability. Examples of physical changes caused by sparks include: -Red/pink eyes without albinism -Purple eyes -Gold/silver fangs and/or claws -Forked tongue -Differently shaped pupils -3+ color heterochromia -Grey/black eyes Examples of traits/abilities caused by sparks include: -Increased senses (one sense per spark. A cat with increased sight, for example, cannot also have something like increased hearing) -Quicker healing -Increased stamina -Lack of need for sleep -Requires less food/water -Weak mimicry -Weak empathy Any other ideas for sparks can be given as well! The things listed here are not the only possibilities for sparks. Sparks cannot be passed down and are canonically a random occurrence within The Barren Valley. The ability to create a cat with a Spark (or perhaps give your already existing character a spark) can be won from things like events, or sometimes event litters will be created containing kits with sparks!
