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).
Creatinine and BUN levels are important indexes to measure how well kidneys are functioning.If creatinine and BUN levels keep higher than normal for a long time, it may prove that your kidneys are not working well.n general,the normal BUN level ranges from 7 to 20mg/dL(2.5 to 7.1mmol/L).However, the normal BUN levels may vary with the lab, and your age. Urea nitrogen levels tend to increase with age. Infants have lower levels than other people do, and the range in children varies.
