DIY Stacked Pots : This is a great idea for annuals, herbs, and just about any plant or flower the drapes over the pot. Try using pots that don't exactly match but provide interest. Yard sales are good place to find pots.
Example: a rabbit could have 1 egg cup of pellets and a pile of hay per day, plus a selection of vegetables. One day it might be a cauliflower leaf and fresh basil/parsley and another day blackberry leaves, fresh grass and a small carrot.
