· More importantly, from your cat's point of view, cats on kidney diets end up in hospital on a drip much less often than those on regular foods.
· Potassium is added to kidney diets because cats with kidney disease often have low levels of potassium. Low potassium blunts cats’ appetites and make them feel unwell.
· Phosphorous builds up in the blood of cats with kidney disease. High phosphorous levels put them off their food and eventually weaken their bones. Cats in untreated advanced kidney failure develop "rubber jaw" - the high phosphorous levels drain the calcium out of their jaw bones.
· Cats' systems become more acidic in kidney failure. Kidney diets help buffer the acidity and improve the cats' well-being.
