Congrats Mandie!! I'm sure you'll love your little guys!!
Here are some of my recomendations:
Feeding a mix of cat food & hedgie food is most recommended by hedgie owners & breeders. The ingredients in quality cat food is better than a lot of the hedgehog foods. Hedgies need a high protein, low fat diet. Good quality cat food is an excellent diet for hedgies.
Hedgie foods like 8 in 1 and Spikes Delight are "good" hedgie foods.
Some good cat foods are Chicken Soup for the Cat Lover's Soul, Nutrience, Premium L'Avian & Wellness. Stay away from Iams (I've read it can cause liver problems in hedgies).
So the bottom line is...it's best to mix good quality cat food & good quality hedgie food. I mix 8 in 1 & Nutrience. With fresh fruit & veggies & mealworms.
Hedgies can have lots of different veggies & fruits too. Avoid stuff that has high fat, high sugar & high salt. Louie loves boiled chicken and small apple chunks. Some hedgies enjoy baby food (from a jar).
And don't forget about mealworms & crickets. Louie LOVES mealworms...he will literally run to get one when I offer it! Mealies & crickets are only used as treats though. They are not the main diet.
For the cage....I would recommend 2 Sterlite containers (most people use these) that you can connect with a PVC tube. Try to stay away from glass aquariums unless you're going to go with a big 55 gallon or bigger one. They need to have a lot of ventilation. The bigger the containers the better but go with what you can fit (& afford!) in your office. Youv'e seen Louie's cage which was really easy to make but not that cheap (about $125)...he has plenty of room to run & play.
For bedding I use Cellsorb Plus and it works great. I would HIGHLY recommend this. It's amazing stuff. http://www.cell-sorb-plus.com/
Most hedgie owners use this stuff and swear by it.
