Hi, I'm Juliet , mom to "PB" our guinea pig we have had since October last year. I joined the forum bc I am looking into getting him a big cage instead of the one from petsmart we currently use. I am looking at one that is 2x4. Is that too big or just right? I am wondering about the bedding for that-do you continue to use the paper bedding or should I use the fleece or whatever that is on the bottom of most of them also where do they use the bathroom in one that large and how is the cleaning done and how often is good? Thanks so much!
