The Fall of Hippolyta

I arrived home Saturday evening. I was getting a glass of water before bed and I noticed dirt on the kitchen floor. Hippolyta, my cactus, was on the floor, her terra cotta pot shattered in pieces. I didn't dare move her until I had another pot to put her into.
The next day I went out and got her a pot she could grow into. As I was cleaning up the kitchen, I could tell a mouse knocked over the cactus. I had unplugged my mouse repeller before I went away and forgot to plug it in again. Now I can barely move the new pot so I doubt a mouse could. I had planned to repot her in the spring since she had grown almost too big for her pot (about 2 feet tall above the pot). Normally a mouse would not be able to knock over a plant that big if it wasn't already so top heavy.
Interesting note: the terra cotta pot left "shrapnel" in the floor boards. The ledge the pot was sitting on was over 5 feet high and obviously hit the ground pretty hard.
