Moving cats from London to Costa del Sol

Hi all,

I will be moving over from London to the costa del sol in the next 12 months and want to bring my cats with me. I have looked into some transporting companies and they want to charge thousands to move the 2 cats for me. I am also anxious about putting them through the flight, etc so am prepared to pay to make it as comfortable for them as possible.

Has anyone had any experience and can give me some advice/recommendations/tips?

I would really appreciate it, so that I don't make a rookie mistake.

Thanks in advance

Darren
