Having used these foods I would say you don't really need to worry about an ingredients list even though I normally won't touch anything that doesn't have a clear, comprehensive list! The ingredients are all entirely natural & based on a lot of research into what hamsters eat in the wild.
I would say though that you may find the hybrid mix a bit too much of a change for her, it contains a lot of herbage which she may or may not eat, it's less nutrient dense because of this so you do need to feed a bit more & it may take a bit of tough love to get her to eat it all if she's a picky ham, any change would need to be gradual so she can adjust to the different diet.
The other dwarf mix isn't so different, it does contain herbage but not such a high percentage & is rather more similar to the type of diet she is used to, the only down side is that not being aimed at diabetes prone species it does contain some dried apple but I used to just take that out, other than that it's fine for a hybrid really.
I do have some of those ceramic items & I love them, so do the hams!
The only thing to bear in mind is that they are very heavy. I had a problem with my Chinese ham who refused to use doors & would burrow under her ceramic house! This would probably be less of a problem with a Russian but still something to think about.
You do need to be careful with the tubes too as they are heavy, I have one of the
dark brown ones with no holes along the side & decided it would only really be safe in the play pen.
I do use
these in the cage & my ham loves them, his favourite place to hide his treasures!
I also have the
sand bath which is very expensive but has been such a big hit with the two hams that have used it so I'm really glad I splashed out on that.
I also had one of
these which I tried with a few hams in the cage & play pen but they were totally unimpressed & more or less ignored it for some reason.
Wooden wheels aren't heavy at all, I have had the rodipet wheels but I prefer the Karlie wooden wheels with or without cork tbh, the rodipet ones have no lip on them so it is easier for the hams to just slide out & both hams I tried with them got a bit obsessed with trying to climb up on the wooden bit in the middle of the wheel, with no lip they would just fall off & out of the wheel so while they are really well made silent wheels for me the design doesn't work, before I switched to the silent runner wheels I did use the Karlie wheels & was really pleased with them.
Cork wheels are lovely & probably a great idea for an older ham but there is less wear on the nails than if they run on a harder surface which is maybe something to think about too.
