In my enclosure there is an area, about 6x8, that is just dirt. I was considering laying sod down but I am not sure about it being treated and sprayed. Any thoughts? Does anyone safely use sod in their pens?
I would lay sod (Bermuda), it is better than dirt. I would ask the people who you buy from if it is sprayed with any pesticides. If it has been sprayed, water it every day and keep your rabbit off it for a week or two.
