How does your cat feel about traveling in the car? Some take to it right
away, and some hate it. I have never traveled long distance with my cats,
but my son has taken his cat everywhere by plane & the cat was fine, even
for the longest trips. His cat, Charlie, always traveled in a portable soft crate
that fit under his seat in the plane. Probably depends on your cat's psysical
condition and personality.

P.s. Charlie's health was good & he was 18yrs old on his last flight.
