Whether summer or winter, holiday time can mean travel. A few years ago, some people moved from California to Maryland with their birds. Traveling with birds is a very unusual experience. But everything can go well with a little planning. There are some good tips for you.
★ The first thing you have to decide is what cage your birds will use. You should make sure that the cage is neither too small nor too big, and can be put into the car easily. If you find that you need a travel cage, get it a few weeks before the trip, so you can give your birds time to get used to it.
★ If your car has the airbag, do not put the cage in the front seat. The force of the airbag even in a little accident could easily damage any cage and even injure or kill the bird inside. The cage should be held in the car with seatbelts.
★ If your trip takes several days, you need to make some stops at pet-friendly hotels. When you stop at hotels during the trip, you must put lots of newspapers under the cage to help control the rubbish.
★ If your travel or moving plans bring you to areas with hot weather, remember that the car will become very hot in a short time in the sun. Never leave your birds in the car alone.
Traveling with birds can be stress-free, and a little planning can make it a pleasant experience.
