Repelling animals from gardens

[JScott]

So I built some raised beds this fall to plant winter stuff like garlic and onions. Since I built them, I have seen disturbances to the surface of the soil when I go out in the morning. Not digging exactly, but places where you can definitely tell something has been there.

I have a cat that goes outside, so it is possibly him, but there was no feces, so IDK. Since nothing is actually digging up any of the garlic or onions or anything, my main concern is that something is urinating in the beds, and the excess nitrogen might be bad for the plants.

Do you guys know of any products that I could use to keep animals out of the gardens? Nothing is coming up yet. It's just bare soil. What do you guys think? I looked on amazon and found a variety of products you spray on the soil surface to repel animals. Do any of them work? Do any of you have a better method for keeping unwanted animals out of your beds? I never had this problem in Oklahoma. I guess we just have more wildlife in Texas or something, but it is a problem I have not had to deal with before, so I'm open to ideas.
