The tap should be tightened, and there should be no leakage, otherwise it will cause water leakage.
Turn the water bottle upside down, block the water outlet with your fingers, and shake it several times to empty the air at the front of the water outlet, so that the vacuum inside the bottle will balance the pressure inside and outside the bottle.
Suitable for fat hamster, guinea pig, hedgehog, squirrel, rabbits, chinchillas
