I dont really know the why enough to help out, but i know of some symptoms. k so cats like to hide it if they are sick so most people dont notice if there cat is sick. they will try to hide (more than normall). Some cats will bump there head against non animate object when they have something wrong too(not the sweet kind against ur leg or the one were they do it against objects to rub there back). Another one is vomiting, smelly pee, not eating, not going to the bathroom, eating there litter, extremly hungry(more than normal) or straining or meowing in the litter box. stuff like that. hope that helped :)
Competition allows science to advance at a faster pace.
Think of it as an arms race: when a country builds one battleship, their enemy builds two. This continues as both countries try to outdo each other. Competitive science works the same way.
