Have you checked the DEFRA site for their approved routes and the requirements?

I think she mentioned in another thread that she was waiting for their PETS passports to become valid, and the route she mentioned (Le Havre to Portsmouth) is an approved PETS route, according to the
EU PETS Routes by Sea page, so I think the only real question here is whether the cats can travel in the same crate - which isn't a PETS/DEFRA question, but rather one for the carrier (Louis Dreyfus Lines), which says the following about traveling with pets:
Can I take my pet (cat or dog) with me on the ferry?
Not all ferry operators have the facility to take pets, therefore you will need to contact us on 08704-580401 or mail@aferry.to before booking to confirm that they are able to take your pet. We can then add them to your booking afterwards (approximately £15 per pet, per leg depending on route and operator). If bringing a pet into the UK, the pet will have to be part of the Pets Passport Scheme. For more information please visit the official Defra website.
Depending on the ferry operator and route, your pet may have to remain in the car for the duration of the crossing, with no passenger access.Mme K, you might try contacting LD Lines directly at their Paris offices:
