I love my girls - Ginger and Epona (nicknamed Pony). They're not just adorable and wonderful fuzzy cuddle buddies - they're also very skilled at constantly eating and subsequently pooping.
Mostly they eat pellets and timothy hay, but they also get fresh treats every day, too. Usually they get an orange slice or a strawberry, but sometimes they also earn their living as living garbage disposals. ;) They love the leafy tops off the celery, carrots (and carrot greens), cilantro stems, strawberries and their green tops, lettuce, cores from apples and pears (with the seeds picked out), etc.
When I built the big wood planter I didn't want to buy that much soil, so I filled it halfway with dirty bedding from their cage. (I haven't found another use for their other bedding changes.) I'm hoping the paper bedding will compost, and their waste will work as fertilizer as the plant roots grow down into that layer.
Part of their cage has a raised platform, and instead of paper bedding it has a towel. Every now and then I take the towel and dump the little piles of poopies into a bucket with green waste from the garden and kitchen. I wish there was a way to separate the bedding from the poopies so I could recover them, too.
Damn they're so freaking cute!
