It's easy, all you need are:
1. Orange peels
2. A spray bottle
3. (optional) Cheese cloths or nylon hose to wring out as much as you can from the orange peels. I tried using a cheese cloth and it didn't work, but you don't really need them anyway.
I used 5 oranges and a medium pot and was able to make 12 oz (in a 14oz. bottle).
First, peel your oranges. I found it helped to score the oranges into quarters.
Next, put the peels in a medium pot and add just enough water for the peels to float at the top. Let the water get to a boil and let it boil for 10 minutes, to release the oil.
After 10 minutes, drain out the water and if you want, use a cheesecloth or nylon hose to wring out the peels for anymore liquid.
Once cooled, pour into a water bottle and spray wherever you like!
I immediately started on these open cords Batman seems to be fond of. His reaction?
And then walked away with his mouth open, aghast I would ruin his fun.
Of course, every cat is different so yours might not react the same way but hey, it's cheap and worth a shot, isn't it? And there's enough to last a long time!
P.S. - Your house will smell ah-may-zing.
