i dont think they would cause kidney failure, but it would cause lots of other problems.
Urinating blood is usually caused by a serious kidney stone - although it is true that other kidney injuries, such as a punch to a kidney, can cause this symptom.
Your kidney fell asleep
No, if your kidneys are not working properly, it would not cause your skin to turn black. Kidney dysfunction can lead to various symptoms such as fatigue, fluid retention, and changes in urine output and color, but it does not directly cause the skin to turn black. Skin color changes can occur due to other factors such as skin conditions, medications, or underlying medical conditions unrelated to kidney function.
In general, no. You can live just fine with one kidney.
urine is normally yellow.
No. That would be impossible, because a kidney infection is caused by bacteria that has to travel up the urinary tract to reach the kidneys. There is no type of massage, not even deep tissue, that would cause this to happen.
Kidney stones are caused by a buildup of calcium in the kidneys, and therefore I cannot see how saliva would cause it.
Grapes can cause kidney damage in cats and dogs. The toxic mechanism is currently unknown. Approximately 32 g/kg of raisins (about 5 ounces for a typical cat) was found to be toxic. (undried grapes would presumably be less toxic, by weight.)
i think that i can not be done and that is not cool. and it would be bad for one to yield out.
Typically this would be kidney beans, but black beans would work as well.
It usually would not do this unless it affects kidney function.
