help

I recently just rescued a guinea pig in addition to the two other guineadad pigs i own and i worry that the cage i currently have for them is not enough. is this coming that could be adequate for them? I don’t have a ton of horizontal space and need to have a cage that has a top due to our cats

Sorry I ask so many questions! Are there certain veggies that are great for baby guinea pigs? I've been feeding mine the veggies recommended for nursing piggies, and the mom has been eating them all but the babies will only eat lettuce. Is it fine as long as the mom gets all of the nutrition...
