The garden stores sell a product that you can spray on flowers to keep rabbits and deer away. I can't recall the name. It's actually a coyotte urine. Rabbits really don't like it. Its worked keeping the rabbits and deer from eating my flowers. Spraying the whole yard might not be as effective but maybe the borders? The instructions also say to reapply after a rain. That may not be easy.
So it's all in the urine to keep them away, but it may be another thing for Oreo to sniff. 
I was actually told that my husband could pee on my flowers and it would do the same thing.  |
