Without for sure Michelle, I would hate to see the result if it went off when kitty was loose and in range. In a crate, secured with the belts might be the best option. I had a fender bender with our OES in the back of the old Blazer, poor dog would never get in the truck again on his own, not easy getting a 90 pounder in when he don't wann'a.
Cat's and dogs in there crates whenever moving.
Hope your journey goes well!!!

So when is this..."old enough to know better" supposed to kick in?
