Does it sound like I take care of my rabbits properly?

I think you're taking car of your rabbits just fine. You're giving them time to roam, cleaning their cages, giving them proper food, and interacting with them. Ive seen people house their rabbits in SUPER small cages and not clean it out regularly like they should. The only thing I would add is that if it is hot outside, put a frozen water bottle in the cage so the rabbits can lay on it. But overall good job:)
