I don't think an 80cm cage would be a good idea and it's well below guidelines - some dwarf hamsters will bar chew. That might sound odd when an Omlet cage is "only" 8cm longer, but the Omlet is also much deeper than 50cm with a difference in square centimetres of 980sq cm An 80 x 50 cage is only 4000 sq cm. The Omlet is around 4980 square cm
Sorry Xena's Mum we're chatting a bit - cage chat is always interesting! Dependng on whether you had a cage or enclosure in mind, Here's what I'd do
If you have the space and finances and like an enclosure style - consider a 100cm Bucatstate 2 - about £140
If you want a cage that's easy to use and set up and manoevrable then get a Grosvenor XL which is about £70
If you don't mind the extra cost and like the Omlet with perspex and it's design, you could get that for £135 in the sale
If you find another cheap second hand savic plaza, you could consider spending £120 on full perspex (replacing the bars completely - it turns it into a tank with a front door). But that would be the most expensive option.
Or something else entirely from the cages list! - I'll link it below but I think those are probably the easiest options for a dwarf hamster.
Anyway if you do decide to buy a new cage - it would be good if you use one of the links from here, as it helps the site running costs
But there still some good second hand choices around too.
