Hi
I brought over several cats 18 months ago.
I used a reliable pet relocater service from abroad and they flew via Qatar airways and my wife picked them up herself from customs.

However not too impressed with customs and handling as the cats were petrified and left out in the heat of summer ( July ) for god knows how long with the rest of the cargo ( no ac or anything )

I doubt a pickup by relocaters in Doha would have made any difference to the way they were handled by customs
