Hamsters are a lot of work. lol
Cage - Try and get a cage from a good quality brand, such as Habitrail, Imac or Critter Universe. :) Keep in mind with habitrail cages that the tubes are tricky for dwarves to get up as they have no ridged on their feet. If you have a tubey cage make sure the tubes are flat. A tank is a good idea for a cage too.
Food - Once again get a good quality, well known seed mix like Hazel (or Harry in the UK) Hamster, or Ecotrition. Another option is lab blocks, they are healthier, but most hamster don't take to them. Good lab block brands are All Living Things, Mazuri, and Oxbow. Avoid food that have lots of corn, sunflower seeds and fruit as they are just fillers. They always need water. Make sure it is bottled.
Treats - Completely optional.
Fruits + Veg - Feed 2x a week for dwarves. Carrots are great. :)
Bedding - Avoid pine and cedar. Use aspen or paper based beddings. Paper based bedding are softer and look nicer but don't mask the smeel of urine and feces as well as aspen.
Toys - You NEED a wheel. You also need somwhere for them to hide and feel safe. Everything else is optional.
Chews - Make sure your hamster has lots of things to chew on like loofa and wood. :)
Clean Cages 1x a week.
Keeping 2 dwarves together - Dwarves can be kept together, but make sure they are in same-sex groups to avoid babies. Keeping hamsters together is always running the risk of fights, so make sure you have a spare cage incase you need to seperate them. If you are keeping 2 together make sure you have 2 of everything, 2 wheels, 2 hides, 2 food bowls, 2 chews.
I hope I helped!! :D

Many of my scaly friends from my original tank from 2011 have passed, except for two! I am in the process of re-doing my tank. :)
