This is a basic guide designed to help you care for your hamster and if followed will ensure that your new Chinese hamster will have a long happy life
General care
Housing
Your hamster or hamsters should have a cage which has at least 1800cm2 of floor space for a single hamster( roughly 6o by 30cms with at least 15cms height) For each additional hamster in the cage add 5oo cm2 however the bigger the better. I personally give all my hamsters at least 2000cm2 of space. Your cage should include a wheel for each animal, water bottle, food dish, house or box and some tunnels and toys. With Chinese hamsters if your are using a wire cage make sure that the bars are no more further apart than 0.7mm as they can squeeze though and escape if narrower.
Wheels
For Chinese hamsters I would recommend a wheel designed for dwarf hamsters ,mice or gerbils . The wheel should be solid and made of plastic, not a wire wheel with rungs as feet can become trapped in these. I would recommend a regular silent spinner wheel.
Cage mates
With Chinese hamsters there is a big debate as to whether they are social or solitary however if you do buy a pair or more there is a fifty percent chance that fighting may occur. Males are less likely to fight than females as the females are dominant. If fighting does occur we stress that the hamsters MUST be separated. Be vigilant if you see them fighting seriously and for long periods of time and they have bite marks cuts etc. Separate them into different cages as the fighting will only get worse. You should always have a large plastic bin or spare cage ready in case of emergencies.
Diet
when you purchase your hamster/hamsters you will have been provided with a pack of their current food and details of the brand. Keep them on this and gradually introduce the hamster mix of your choice. Make sure to give your hamster/hamsters some fresh food at least once a week however introduce fresh foods slowly and gradually into their diet. Remember fill up the food bowl once every two days. If you fill it up every day the hams will pick eat and will only eat the bits they like. It is also important to make sure your hamster has access to fresh water and water at all times so ensure your water bottle is in easy reach and frequently check it is working properly. Never feed your hamster these items
Kidney Beans (raw)
Onion
Potato (raw)
Potato tops
Rhubarb (raw)
Rhubarb leaves
Tomato leaves
Tobacco
Alcoholic drinks (never give your hamster any drink accept plain water or milk) Some hamsters do not tolerate milk and kitten or soya milk is a better choice.
Taming
All our hamsters have been tamed and have been handled regularly from 3 weeks old but here are a few simple taming tips to help you tame your hamster/hamsters which will help your hamster get used to you. Put a small container like a cup into the cage with some treats inside and let the hamster/hamsters climb in. Take them to a low safe area such as a bed and let him/her climb onto your hands and handle by running hand to hand through your fingers. Remember a hamster only bites because her or she scared or your hands smell of food so be calm and patient.
Play pens
Playpens are OK and are a great idea for giving your hamsters something to do when you are cleaning out (as long as they are supervised by another person ) or are just a nice way of watching and spending time with your pet/pets I personally use VHS 'on their side' tapes to make play pens as you can make whatever size of pen you like and can change it to any shape or size. Don’t use DVDs they can be pushed over too easily With commercial play pens if wire ones make sure the bars are no more than 0.7 mm square apart or you risk your hamster getting stuck between them and seriously hurt. A large plastic bin also makes a good playpen.
Exercise balls
All our hamsters are exercise ball trained from four weeks old however some hamsters do not like exercise balls if so we will add a note on to the pedigree if this is the case. If it says that your hamster/hamsters don’t like exercise balls it is in your best interest not to force your hamster to use an exercise ball. However if your hamster likes exercise balls the we recommend a small ball designed for dwarf hamsters which is clear hamster have poor vision. Coloured balls make it more likely that your hamster will bump into things.
