Proper cage setup?

[Lovelypigys]

Hello I was just wondering if anyone had any better ideas of how to utilize the cage space my Guinea pigs have.
The purple one is a 6x2 with two males, and the grey is a 5x2 with a 1x2 loft housing two females. I want them to have plenty of popcorn room. Do these seem suitable (photos attached.)

They look like they have got a lovely amount of space to run about.
I would, however, add considerably more hay (in more areas) in both cages.

Thank you! I have just refilled the hay corners and put some hay into the burrow boxes

They look like really lovely cages and are a good size for your piggies.
Other than additional hay my only comment would be you could add a fleece forest in one of the corners (or even just a few fleece strips.
I made my own by cutting up a fleece blanket and my piggies always loved running through this.
