I do have raised garden beds which I do assign tenants should they feel the need to grow veggies (no Marijuana growing, Colorado folks, lol). 

Some of these are indeed therapeutic for owners; many times a pet owner simply pays a fee online for a "certification" that allows them to get around common fees associated with pets (housing, airlines, etc).
