When it comes to your cat's safety and comfort when flying via airline, at The Sunshine Home we have the knowledge and experience to do it right!
We begin by recommending the best carrier (also called a "crate") for your cat to fly via domestic (US) airlines: the PetMate Vari Kennel Deluxe or Petmate Sky Kennel "200 size" (the one pictured at left, not the "Junior" version). We believe it is the best-made carrier for this purpose. It is very sturdy, with a secure locking door, and has excellent ventilation. And at 28 inches long, 20.5 inches wide and 21.5 inches high it seems to offer the purr-fectly sized space with more headroom than most carriers in this class.
And because preperation is just as important, we've created a instructional video on YouTube about getting your carrier ready for the airline. Click on the link below to view it.
And always consult with your veterinarian before shipping the cat. Most airlines will require, at a minimum, a current Health Certificate from your veterinarian (stating the cat is healthy and cleared to fly) and a current rabies vaccination certificate. Check with the airline to make sure you are following their rules and regulations.
This information here is basically geared towards domestic (US) air travel. If you plan on shipping your cat to, from or through other countries check with the airline to see what they require or recommend.
