Cats DO NOT need to visit a vet before returning to the UK for worming, tick treatment or a health check. As long as they are micro chipped and have their rabies vaccination boosters up to date, which is recorded in the EU passport, you will meet all the requirements for taking cats back to the UK. All the information is on the DEFRA website, maybe there are some vets who are not familiar with the new regulations. We have been back and forth at least 5 times with our cat this year via Brittany Ferries and Eurotunnel and have never had a problem with re entering the UK.
