Hi! Congrats on getting a hedgie soon!
A wheel is a MUST for a hedgie. They have a tendancy to become obese and it's very important that they have a wheel to excercise on.
IMO, Lowering the shelf is a great idea but you can leave it - hedgies love to climb! I would make the ladder at not such an angle though so it's easier to climb.
But, the cage overall looks much too small for a hedgie. Sorry, jmo.
And is that flat white thing a food or water bowl
? He/she will tip that in a second flat! You'll need to get a crock type of food bowl
- they work the best. The small ones are cheap.
Linoleum in a great idea.... that indoor/outdoor carpet would be permenently pee stained in one week!
If you have any other questions, please feel free to ask. It's great that you're getting prepared and trying to figure out everything you'll need!
