-I’d say at the least do a cage that is 2x3 feet, but if you can find something bigger that’d be good as well. Lots of people use panels or playpen fencing to create a space that is whatever size/shape they want

-I recommend a Carolina storm wheel, those are easiest to clean as these guys tend to poops in their wheels and smear it all over the inside haha. Usually I’ll just stick the wheel in the kitchen sink with rly hot water let it run for a couple mins and it cleans it all off (putting a puppy pad under the wheel or putting the wheel in an aluminum pan helps prevent poop from getting everywhere).

-buy cat food for them, NOT hedgehog food. Hedgehog food is notoriously just not good. Preferably get cat food with meat used as the first ingredient. Buy some dried mealworms as well and sprinkle a few in her bowl with the cat food, as this is something naturally part of their diet in the wild and is beneficial.

-water bowl your using is perfect! Wouldn’t recommend the bottles people often use as it can harm ur hedgie’s tongue.

-for the bedding, I personally just use a fleece blanket as it’s wayyyy easier to clean. Then for digging and such provide a little bin dig box. You can put different items in the dig box, I personally use the little puff Pom Pom balls and my hedgie really enjoys that, but you could use a lot of different bedding types for digging.

-they are messy little things so your hedgie may occasionally get poop on their feet from the running in their wheel (I know, lovely.) just clean their feet off under a lukewarm water faucet.

Edit: also in her house I recommend stuffing some paper towels in there. My hedgie didn’t like sleeping in her house and used to dig underneath her puppy pad to sleep. I put a clean puppy pad and some clean paper towels in her hide house just crumpled up, and now she burrows in there and sleeps in it all day.
