Could have used this a few months ago. Moving 5 cats via Grand Cherokee over three days and 1500 miles was not fun for me or the cats. Think 3 days of the Anvil Chorus done by cat yowl.
I also think it would've been considerably less stressful on the cats, too. They had to be recaptured and crated multiple times, positively freaking out each time. They still don't act right.
