Hiya Cat,
i completely understand where you are coming from - these cages look like they would be great fun for a hamster, they are colourful, full of different compartments, interesting to change around etc. - but in reality these cages are made to appeal to people, especially children, and they have been made with no consideration to the poor hamster that has to live in them!
I think almost everyone that buys a hamster for the first time is interested in these cages, because of how they look - i had a similar setup myself when i first kept hamsters, but once you have a look round at the forums and reviews of these cages, you can see that they are just not suitable, no matter how good they look! and, as Souffle says, they are not even as big as the recommended cage size by the RSPCA and NHC - so obviously thay can not be used!!
Luckily, you have joined just at the right time, and you havent actually got a hamster in that cage at the moment - so the best thing you could do is to buy a new cage which is big enough for a Syrian hamster - you have asked for our oppinions on the cage and you have been given people's oppinions - please take head of what has been said, and please do not put another hamster in that cage.
Where are you buying your Syrian from? I saw in your previous post that you had trouble with a hamster from a pet shop, so i would hope that you are getting your next one from a reputable breeder. If you do get your hamster from a reputable breeder then the chances are that the hamster will definately grow way too big to even be able to fit in those tubes!!
Please think of the hamster and get him or her a nice new cage which is big enough for him or her to be happy in
I understand about the cost of the cage you have there too - they are rediculously expensive, even though they are not really suitable for any hamster, but as you say, you have had two hamsters living in this particular cage, so i would think that you would have had your money's worth out of - so the best thing to do would be to dispose of it.
If you need any help or info about which cage to buy then please just let us know
