When your cat rubs his face on an item like a chair, wall or coffee table, he leaves his scent behind. Cats rub their faces on things for many reasons, depending on the context or object being rubbed. Cats have multiple scent glands on their heads. They have glands located around their mouths, chins, sides of the face, neck and ears. When a cat rubs his face on an item, he leaves his scent behind. The act of a cat rubbing his head on objects is called âbunting.â The height of the object determines which part of his head a cat will use to leave a scent mark on an item.
Increased blood urea nitrogen (BUN) may be due to prerenal causes (cardiac decompensation, water depletion due to decreased intake and excessive loss, increased protein catabolism, and high protein diet), renal causes (acute glomerulonephritis, chronic nephritis, polycystic kidney disease, nephrosclerosis, and tubular necrosis), and postrenal causes (eg, all types of obstruction of the urinary tract, such as stones, enlarged prostate gland, tumors).
Tumors affecting the gall bladder, liver or bile ducts could be responsible for elevated levels. An allergic reaction to the blood received during a transfusion can also cause the levels of bilirubin to rise in adults. Cirrhosis of the liver is another reason for elevated bilirubin levels.
