I was thinking more of cages about the size suggested (Duna Fun large) - eg Savic Mickey 2XL and similar
Didn't realise it was a robo either! I will wait for robo owners to reply but the standard duna multy or Kerry Terrarium are probably good options and Standard Duna Multy only £33. If set up to give lots of cover and not too exposed.
This Robo breeder has a good range of suggestions - the gabbers she mentions aren't really available any more but they are similar to the duna multy.
