Taking Your Pet Abroad - The Pet Travel Scheme (PETS)
 
Pet Travel Regulations 
Pet Travel regulations enable you to avoid putting your cat or dog into quarantine when you travel to certain countries (most countries in Western Europe & Scandinavia). To qualify for exemption from quarantine, you must meet various conditions relating to your pet´s health.
 
NOTE: Pet travel rules changed on 1 January 2012 when the UK brought its procedures into line with the European Union. We strongly suggest that you visit the government website at GOV.CO.UK to familiarise yourself with the most up to date information on this subject.

Other considerations 
Take your pet for a health check by your vet in advance of your journey. Get advice from your vet on pregnant animals.
Speak to the carrier in advance to ascertain the conditions that your pet will travel in and to ensure that you have the required paperwork.
Do not use sedatives unless advised by a vet.
Give your pet only a light meal about 2 hours before travel.
Check with the carrier that your pet will have full and constant access to fresh water.
Use a container which enables your pet to stand, sit and lie down in a natural position, and to turn around easily. The container should contain absorbent bedding and provide ample ventilation. A familiar toy can help your pet get used to the container.
Ensure that your pet will not be exposed to extreme temperatures.
Try and match your pets sleeping patterns by travelling overnight where possible
