Can anyone recommend me a cat-proof tank for a Syrian hamster?

I currently have this one as i had intended to get a dwarf, but a cute Syrian caught my eye instead. www.petsathome.com/wcsstore/ConsumerDirectStorefrontAssetStore/images/products/large/24231.jpg

It's much too small for my Syrian, and I need something with a similar style, but bigger. Because of my cats, it needs to be a tank with minimal bars rather than one with all bars.

The hamster tanks on PAH all have terrible reviews and the tunnels etc look more suited to a dwarf.

They need to be quite big I think. Can you get a large aquarium with vented lid?

Look on omlet for super hamster cage ( but pricey), might give you an idea though

Thanks! I'll have a look. Never even considered an aquarium.
