Guinea pig C&C cage?

[tryhard]

Currently have a 2x3 with a 2x1 lift C&C set up for 2 females but want to add a third pig to the herd and need to find a way to expand the footprint, just wondering how others had their indoor piggies set up?

I have a grid set up (not C&C but grids I got from Costco) they're 14" square.

Mine are far far too lazy to use a ramp , I have a 4x2 grid run (so 56" x 28" ) with a partition to put their sleeping box . This is for my 3 adult group (my two girls group have a 24" x 48" cage, plastic base).
They sleep in these on winter nights in the small bedroom.

Have you got spare grids? Can you adjust the liner if you alter it?
Bear in mind if you get a piglet you might need to overlap slightly if the squares are too big.
Have you measured out how much floorspace you could make with the grids? You can add boxes and tunnels to sleep in.

Have you asked your piggies if they want another herdmate (Mine are very happy with their neutered boar husband - husband number 2 after our GP3 died) but less welcoming to our new girls ( GP4 and GP7 are very strong feisty sows )

I've got a metal pen I'd like to put a liner in to give pigs more room (hesitating over buying c&c grids as the pen is already the same area as the largest c&c 6x2 layout) - what could you buy to line a pen or to put under tryhard's grids, if she buys some extra grids?

70, what did you get from Costco?

They were in the office bit millimat , grids 14"x14" with the circular fasteners (that I'm too cack handed to fasten) , I use those cable ties and clip the ends.

I think it was 2-3 years ago (we had Dylan GP3) I've been looking out for more .

Thanks all, in fact I've been thinking about how wise it is to get a third pig, my girls are very settled, one is much more dominant than the other, it never occurred to me that a third would upset or change the dynamic but now I'm not so sure. And theres the expense, one girl has just cost us nearly £350 in vets bills. I feel they're cage isn't big enough for them as it is, during the day they are in a 2x7 playpen but this drives my OH nuts as it's just in the middle of the utility room taking up space and I put it up and take it down every day, which is a pain. I could expand their current cage by half a grid, but I'd need to get extra corex for the base, that'd take it to 2x3.5, not much better but a bit better.
