Your brother would be a better option to a cattery, imo.

Unfortunately my cats have to go to a cattery. The cages they have are spacious and this time I knew I needed two cages and worried about splitting them up. I didn't have to split them up the cages opened up so all three cats had access to two cages. I could have requested three cages but that really wasn't necessary.

There are good catteries around its just finding them.
