Water Bottle & Food Dish
You should hamster needs constant access to water and this is best provided by using a bottle. You may also want to give your hamster a dish to serve its food on.
A bottle is a better choice than a dish for your hamster’s water as it will keep the water clean and prevent it from spilling into the bedding. Water trapped in bedding can potentially cause fungus to grow which can lead to infection. Water bottles specifically designed for hamsters can be bought, and you should place the bottle at least three inches from the floor, or a bit lower for dwarf and Chinese hamsters, where your hamster can reach it standing up but not easily climb on top of it.
