OK, so yesterday we discovered that after 6 years of going into the crate whenever I left the house without any problems, Sienna decided that she was a big girl and deserved to be released. Since she didn't seem to have success in communicating this to me, she decided to release herself.
I have class on Thursday also, so I removed all the loose pieces that she had been working on, turned the crate around so the hole she had made was flat against the wall, let her into the crate and shoved a piece of furniture over slightly so it was against the other door. The part of the crate that faced the room was the back, solid wire, no door.
I came home to this:
This is a NEW hole and shows what a 4 hour crate attack can look like. She couldn't get all the way out, because the crosspiece is still in place, but she had removed enough verticals to get her head out the hole.
Now, just so the SPCA doesn't get me, she was in NO distress and could remove her head from the hole without a problem, so I grabbed my camera because I couldn't describe this.
I am now going to go search the web for bulletproof crates.
