Humans aren't made to screen stare in a vegetative state all day. 

You could grow fruits and vegetables to sell at local farmers' markets, or start a subscription-based service that delivers fresh produce to local customers.3.

I know, it sounds irresponsible to not know exactly what one has purchased, however, this little portion of the property was tucked away behind a wall of trees and vegetation.  

Any crack 1/4" wide is like a revolving door to a mouse, so it may be a losing battle in an old house, regardless of cleanliness, vegetation, etc.

Vegetable raised bed above for tenants? 

@Theresa Harris They did maintain it sometimes (in the summer when they grew vegetables) but I don't believe they were happy when I cut down the trees in the lot (had to they were just really overgrown and not manageable). 

For our multiplex properties we take care of everything else as well, except for the garden beds if tenants want to plant flowers/vegetables and tend to them.

Let me give you my perspective on the question itself and then I'll share what I have done.Your question is perfect, but super hard to answer because it is like asking "which is better - fruits or vegetables"?  

Is there any vegetation that would be harmful to your pet?

Eggs, butter, fruits, vegetables, herbs, peanut butter, many condiments, jam, honey, breads, etc can all be left unrefrigerated.
