Rat urine, like human urine, can vary in different degrees. Normally, it will be a light yellow. If the rat is highly active, it will be taking in a lot of water. This may result in urine that is lighter or clear. This is absolutely normal in most circumstances. If the rat is drinking excessively and is not active, that could be a sign of trouble. Older or dehydrated rats may have darker urine.
The brown rat is a rather large true murid and can weigh twice as much as a black rat and many times more than a house mouse. The length is commonly in the range of 20 to 25 cm (8 to 10 in), with the tail a further 18 to 25 cm (7 to 10 in), thus being roughly the same length as the body.he brown rat, also referred to as common rat, street rat, sewer rat, Hanover rat, Norway rat, brown Norway rat, Norwegian rat, or wharf rat (Rattus norvegicus) is one of the best known and most common rats.
