Hi, if you are worried about putting your loved moggies in the cargo hold perhaps you could look at DME/Paris on Air France (if they fly there) and then take either taxi back to UK, or rent a car in Paris dropping off at home in UK. It isnt the most straightforward way but if you calculate the cost of transporting cats in cargo plus the risk.
I have friends living in Budapest who did exactly that as their cat was quite elderly and they didn't trust the cargo hold.
