Guinea pig housing query

Sorry, I know it's the wrong kind of 'rabbit' but I know lots of you keep GPs too. (I did try the GP Rehome forum but I didnt like the format/want to register...)

My friend has just acquired a GP, who is being temporarily housed in a bog-standard hutch. She's realised this isnt really suitable for what she wants and is now considering an indoor cage.

Obviously the bigger the better, but she has limited floor space. Can GPs cope well with two storey cages like these??

My piggies live in a two storey hutch and love to zoom up and down the stairs.At first they couldn,t figure it out but it didn,t take them long

my guinea pigs used to have a 2 story hutch and got on fine with it
