Well, I made a REALLY big oops. I learned never to put a Jack Russell into a vari kennel that contains a sleeping cat.
Thankfully, everyone is ok, but they were in there together for over an hour. How did this happen? I have no idea. I was moving the crate all around and put toys in there. Didn't see or feel the cat curled up on the blanket inside. About 5 minutes later, I heard barking (not unusual), and then some hissing (also not unusual, as sometimes Nella will hiss from the outside of the crate if Digit is inside staring at her. Then it was silent, so I didn't think a thing of it. When I went up to let Digit out, imagine my surprise when Nella came bounding out after her.
I can laugh at my stupidity because no one was even slightly hurt, but BOY could that have ended badly!
