You may find that a C&C cage like gpiew's (or even mine, even though both are quite big and have space for more than two gps) gives you more flexibility to divide and reassemble a bigger cage, so your boy could live next to his prospective girls while waiting and not feel so lonely, but you would be able to convert the whole setup into one bigger cage once he can move in with his girl(s).
One pack of grids consists of 17 35cm/14in square grids, so you can build anything from a 2x4 grid setup with a mezzanine floor to a big 2x6 or 3x5 grid one story cage. If you have the space, you can build a temporary 2x5 grid cage with a divider in order to house Patch separately next to one or two girls.
One pack of grids can cost as little as ca. £20 incl. delivery. For temporary housing, some cheap lino will do the trick. Otherwise we recommend correx from a local signmaker's.
Have a look in the cage and hutch gallery at the top of the housing section for ideas!
