So this morning, I had Zeus out while I got dressed and ready to go to the barn to visit my horse. I let him out for about half an hour, then put him away with his breakfast waiting for him in his cage.
I got home, sat and watched TV for about 20 minutes, Zeus is napping in his cage. Then I get into the shower. I’m in the shower.. and I hear this quiet thump thump sound. Alright, whatever, I think maybe it’s one of my neighbors (apartment) and try to ignore it. Then a few minutes later.. THUMPTHUMPTHUMP. Ok, that’s DEFINITELY coming from my apartment!
I’m thinking like a robber or something is in my house while I’m in the shower! 
So I get out of the shower, and slowly turn the knob of the bathroom door. I peek out, and Zeus is sitting next to his cage.. not in it! He looks over at me like, “Oh hi mom, I’m out right now! I’m not in trouble am I?
“ So I’m thinking.. he jumped out?! He’s never jumped out, what gives?! Then I look at his cage.. and the door is open about a foot. 
Basically, I forgot to lock the cage door before I left for the barn! Meaning Zeus was home alone with the cage unlocked for 3 hours.
The funny thing is he didn’t get out until I got home and jumped in the shower.. he HATES when I go into the bathroom and close him out. Oh, and that THUMPTHUMP sound was him digging at the door.. he also chewed a very small hole in the carpet…
But really I couldn’t be mad at him, it was my fault for leaving the door unlocked!
The funniest part was, when I found him out he was sitting all innocently right next to his cage, when the entire time I was in the shower he was digging and tearing at the carpet to try and get in. You didn’t fool me stinker, that hole in the carpet didn’t get there by magic! 
So yes. Long story short.. double check you lock the cage of your bun’s enclosure!
