Why is the cat water dispenser easy to be green?

The water has been left for too long and has grown green moss, especially in hot summer.

It is easy to change color in summer, so it needs to be changed frequently when feeding cats and water. Don't leave it for too long, it is easy to deteriorate and affect the health of cats. The water that the cat simply drinks will not turn green, and the cat will be clean. Green water will not be drunk by cats. Cats like drinking flowing water very much, which will attract their attention. There is basically no way? God, sex, running water? But if you must stop it, you can try adding a little strange smell (such as stinky tofu juice or wind oil essence) to the feng shui wheel. Cats are very sensitive to taste, and when they can't stand it, they never drink it again. (But remember not to put anything you can't drink, in case the cat tries to get poisoned by mistake. )
