I say this with only kind intentions even tho it may sound harsh:
I do find it conserning that you put the looks of an cage before the wellbeing of your hamsters! That is the most careless answer ive ever read from someone using those kind of cages and i find it very sad!
You obviously cant have reseached hamster cages well because all the members here who have desent sized "boring" cages (80x50cm or more) have really happy hamsters! It dosen just depent on the size of the cage you know!! Size is important yes ofc, but so is a desent sized wheel or flying saucer, toys and many activities like running, climbing, digging and bathing in sand etc!!!! And not to mention time outside the cage!!!
The "boring" cages on here is nowhere near what is it like in the petshops! you just check out this link and then tel me they live in same conditions at petshop hams:
Let's see your cages (from January 2013)
We can dream about many things through life, but a responsible owner just wont put their dreams before the wellbeing of their hamsters! It just isnt humane or sane to do so IMHO -____-'
Your dwarfs may be getting along fine now, but one day you will find one or more of them half eaten by one of the others, and you will be devostated!
Is it worth it just to have a cage you think is cool?
I understand you used ALOT of money on that setup, but cant you just take our advice and listen to what we say?
That cage is just not safe for your hamsters!
Besides being expensive they have these cons:
-poor ventilation
-They make pairs or groups turn on eachother because of territorial fights
-They smell worse because of air not getting to circulate around the cage
-They are a pain to clean
-They have so many parts that if one gets broken of will you find your hamster and the hole it got out of in time?
-They get build ups of urinegasses and this can make your hams sick, it literally makes it a
amonia-gasschamber
-It makes it hard to check on you hamsters health
-And worst of all NOT SAFE for ANY hamster to live in permanently!
Im totaly with kyrilliondaemon and vanilla-yazoo on this, you are infact endangering your hams with this cage, even tho you think it looks cool or nice or whatever
Habitrail/crittertrail cages are maid to make money NOT with the best of the poor animal living in that thing in mind! They are made for kids, not adults who wish their hamsters the best!
And yeah; Syrians are not to be paired with ANY type of hamster, they actually end up killing each other more times than they get along.. even tho you may have heard about it working for some (excuse me) ignorant people...
I am sorry to be blunt but this is all facts that im telling you and im really worried for your hams with you being so incapable of listening to any of the warnings and advice you have gotten
I hope you change your mind about this cage and buy a big "boring" cage for you hamsters, you must love them right??
