First time in the cattery - any tips

[MrsFogi]

So the FogiCats are going to a cattery for five days over Christmas. Their/Our first time. Any tips on what to bring (or not bring) to make their stay a happy one? Or indeed any tips at all?

I take my cats brushes, favourite drinking vessel and an old t short that smells of me. Fatty cans snorg were almost identical so I also wrote instructions on how to tell them apart. Do not forget the vaccination certificates. And flea and work them before they go. I think my cattery looks after my girls better than I do!
