To add to the unanswered questions on this thread/some advice:
If you go with a detolf, you must use a lid. The detolf is very shallow (only 14” tall), which most hamsters can climb out of with a little cleverness, especially if you pile up the bedding on one end.
Other cages options like bins are great if they’re available to you, but I hear in Europe good bins are harder to come by. Checking out ZooPlus May be worth a shot; they have some great barred cages like the Alaska and the Barney that would definitely work for a dwarf. Granted, they’re not as large as the detolf, but they’re a lot more sturdy and don’t require modification.
Either way, be sure you fill the cage so your hamster feels secure. There should only be enough space for your hamster to weave around each toy; large open spaces are not recommended, especially for new hamsters. DIY is a great option; YouTube is full of ideas.
The 110qt bin is actually only 450sq in. The dimensions listed are the top dimensions and, since most bins slope down to the bottom (including this bin), the actual dimensions can be up to 300sq in smaller than listed in some cases!
For red pepper, this depends on the type— hot peppers should never be fed whatsoever as hamsters can’t tolerate spiciness, but red bell pepper can be fed every 1-3 days. A 1cmx1cm chunk is a good size
