They have never even stood up with front paws on it. Mine aren't climbers, but wow, it certainly would hurt the feet if they did try it. The chicken wire comes in different sizes. We live in a very foggy area, so we do have lots of wetness almost every night and morning, not to mention we are close to the ocean and have the humid breezes off of it. Not sure what the chicken wire is made out of, but since it's made to house chickens I'm sure it's made not to rust out that easily. We don't have one rust spot so far. |
