Is there a wire hamster cage with a hole that you can put a tube in to connect 2 cages?

Sorry, I probably could have been more clear on that, but I only get a limited amount of letters.
I have a glass hamster cage that has 2 holes for tubes to go through, but I can't find any wired cages that have it. It has to have horizontal bars and be big enough for 2 hamsters. (Yeah, I know hamsters are loners, but I know how to get them to get along)
Answers:
First off, if the hamsters you have aren't dwarves, they shouldn't be together. I knew somebody who thought they could make their syrian hamsters get along and live happily ever after together like you, but one day they got up to feed them, and one had killed the other and was eating him. You don't want that to happen, do you? because it will.
Second, in regards to the cages, you can try to attach a storage bin to the hamster cage you have now. They are much cheaper than a wire cage and much roomier for the hamsters. You can attach them easily too, just make a hole in one of the sides, attach the tube and whalah, you have a homemade hamster cage. Just make sure that they have plenty of ventilation by drilling holed in the walls or in the lid.
Good luck and please separate them if they are syrians (teddy bear, golden hamster, black bear, or panda bear).

Yes there are. They are at Petco and are made of plastic but do have the wires. There are kits that come with food and a water bottle along with the cage and the company that makes the cage is "My Super Pet."

Yes, there are cages like this, they aren't the habitrail/crittertrail kind, they are honest to goodness wire bar cages with tubes, you go onto Ebay.com and type in Hamster cage, and scroll through, there will be a lot of the same listing, it is an Ebay Store, they even sell pairs of cages with tubes connecting them. The single cages come with A LOT of tubing too, way more than a habitrail kit comes with. The price varies, they will have cheap prices but a little bit high shipping, this is to balance the price out so they still make a profit. And no, I am not the owner of the store, I just was shopping through ebay yesterday and found them.

Cages like Crittertail usually are part wired and part plastic - I've been very happy with this brand. And most of the other brands of cages use the same type of tubes - like S.A.M. - which are normally all-plastic.
Hartz makes a line of all wire cages that are generally NOT compatible with those above. The tubes are larger too and don't work well with dwarf hamsters. I would avoid these Hartz cages - although you can do some tricks to join them together.
I like the Crittertail cages and recommend those! They have wire sides and also doors in the front/sides making it easier to handle your hamster.
