I've had big problems with rabbits eating my semps in years past. I think I mentioned last year making chicken wire hats for my semps which successfully kept the rabbits out. Since my semp gardens are a lot more extensive this year, I bought more rolls of chicken wire and put chicken wire fences around all the semp gardens and made many many more hats for all the new pots.
So far it's worked, even though we see two or three rabbits in the yard every day. With this drought, I don't know what they are finding to eat. The semps are the only thing green in the yard.
p.s. My cats are good hunters, but they don't go after the large adult rabbits. Too big and too fast.
