Rat urine can be harmful. Wild rats can carry many different diseases which are transmitted to humans in their urine. The urine smells similar to other animals' urine because the main components are water and urea. Urea is high in nitrogen and forms ammonia when it breaks down giving it a strong odour. Rat urine also contains minerals such as calcium which can leave a chalky residue when it dries. Some people describe the smell as 'musky'.
Ammonia can cause burns to skin if it is in a strong enough concentration. If the cage of a pet rat has urine deposits on it these can be removed by mixing vinegar with water in a one to four ratio. Spray this on and leave it for about an hour. Wipe it away and rinse with plain water. If any residue remains you can scrape it off with a blunt knife.
The smell of rat urine in a room when you don't have pet rats could be a warning that you have some unwelcome residents. Rats can cause a serious problem by chewing wiring, damaging clothing and ruining the food in your kitchen. There are many different traps and repellents available on the market. Some are more effective than others but you've only got to have one rat which is resistant to your method for the problem to continue.
