Hamsters are relatively cheap to purchase. You’ll spend far more money on their toys, cages, and healthcare. [2] X Research source

If a hamster has wet fur around the rump, be especially wary; this is a sign of “wet tail” — a bacterial disease that spreads quickly through contact with other hamsters. The fur must be dry and clean. There are antibiotic treatments for wet tail, but if you just now picking out a hamster, try to find one that is healthy. [3] X Research source

An IKEA Detolf is an excellent choice too. Alternatively, the “cat tray with a wire top” type of hamster cage does have good natural ventilation. Make sure your cage is not in direct sunlight as your hamster could overheat due to the bright rays magnifying on the aquarium glass. Unless they’re second hand, aquariums can be expensive. You can also purchase wire cages, which have great ventilation, just ensure that they are big enough. Many people make DIY cages, which are wallet-friendly and are great to make. One of the most popular and cheapest DIY cages is the bin cage, which is made with a 105-quart bin and mesh attached to the lid.

Even dwarf hamsters cannot be housed together. While they live together in the wild, this is for breeding and survival purposes, neither of which are needed in captivity.

Softwood shavings such as pine and cedar are just not good for hamsters, as they cause many health issues. They can cause respiratory problems and may contain harmful oils. However, aspen bedding does not contain the same harmful oils and is perfectly safe for your hamster. Never use cotton bedding. This is very dangerous for your hamster because it is indigestible, and strands of the bedding can wrap around limbs and extremities cutting off circulation and potentially killing your hamster.

If you want to change your hamster’s food, wait a few weeks after taking it home; then gradually introduce the food over a period of ten days. Your hamster is a hoarder, so it’ll keep private stashes. Removing these stashes can be very stressful, so if you are worried about the quality of their stored food, remove it and replace it with fresh food exactly where your hamster had it.

To tame your hamster, place your hand in the cage. Let your hamster sniff it and explore it. If the hamster nips gently and not out of aggression, pull your hand back gently, but immediately let it explore your hand again. This will help the hamster learn that the hand is nothing to bite or fear. Next, place treats in your hand; seed mixtures are good for this because as a supplement to the pellet or block-type diet, hamsters love this food. Your hamster should become used to climbing onto your hand, learning that the hand is something to climb into. Gradually move the treat up your hand, as your hamster will become more and more comfortable climbing onto it. If your hamster is showing good progress, try to let your hamster climb onto your hand and offer it treats right after it has. Your hamster will see your hand as a good thing. This time, let your hamster climb onto your hand and lift the hand slowly off of the cage floor. Your hamster may be frightened at first, but speak softly and offer it treats to make it feel more comfortable. Sit on the floor during this step, as your hamster may decide to leap out of your hands and can be injured once falling from about 6-8 inches (15-20cm) off the ground. [16] X Research source

Hamsters have a necessity for a solid wheel. If the wheel has gaps in it, it could injure the hamster.

Make sure that there are no dangerous items that the hamster has access to (such as electrical cords which your hamster will chew on) and that the room is escape-proof.

You can also use a vinegar solution to clean the hamster’s habitat. [19] X Research source
