Vasopressin (Antidiuretic Hormone). Vasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to, and released from, the posterior pituitary into the blood. AVP has two principle sites of action: the kidney and blood vessels.
The Siberian cat is very exotic, but itâs kittens are adorable. A cat with a big personality and a big popularity in many parts of the world, their kittens are a big part of the reason that so many people adore this breed.
I think the reason they are so ugly is the same reason kittens and puppies are so cute. A kitten, for example, is a miniature cat. They look just like a cat, only smaller. Everything is there: tiny whiskers, fur. Human babies are gross. Their heads are large and out of proportion to their bodies.
