Cats â Ailuromancy. A cat licking its face. There's rain coming soon. There will also be rain coming if you see a cat sleeping with its back to the fireplace, or if the cat is climbing the furniture. A gray cat. Good luck. Finding a cat on a boat. This is a sign of good luck.
Onychomycosis, more commonly known as toenail fungus, is a progressive disease that is often ignored due to the lack of pain or other symptoms during the initial stages. Typically it is caused by tinea species (fungus), but it can also be caused by candida species (yeast).
Injury to the nail or illness anywhere in the body can cause white areas in the nails. If part or all of a nail separates from the nail bed (shown here), it can appear white -- and may be due to an injury, nail infection, or psoriasis. If the nail is intact and most of it is white, it can sometimes be a sign of a more serious condition including liver disease, congestive heart failure, or kidney disease.
