Pet Flight Inc. did all the work for me!
I sent two cats from Toronto to Manchester UK through Pet Flight Inc. The cat transport was AMAZING, completely seamless, all I had to do was fill out two forms and call to confirm the drop-off in Manchester. The cats arrived about 15 minutes after I got to my new apartment, and they were both healthy and in good shape. When I let them out they weren't fazed at all...they just went about daily life like nothing had ever happened. Pet flight was so organized the entire time. I sent in an email inquiry and they contacted me within about 5 hours. They had a quote for me 24 hours later, and they gave me very useful advice before I purchased anything from them. They gave me easy-to-follow instructions every step of the way, and after the first two forms, all I had to do was sit back and relax. They picked the cats up from my house in Toronto, and got them cleared through UK customs in advance. Their quote was very competitive, on the low end of all the other quotes I got for this type of service. It was worth every penny.
