Just an afterthought -- If you are going away for a honeymoon, make sure that whoever is left to care for the animals is very well instructed about how to keep the animals separate. You may want to designate one room (which two cats, it has to be a larger one), cat-proof it as well as possible (for example, all breakable temporarily banished to cupboards and drawers, the bed stripped and all mattresses or cushions bundled in HEAVY plastic and then covered with lots of blanket, rug, or cloth material to give the cats something comfortable to be on), toys on the floor to give them something to do (be sure they are not the kind the cats can swallow, because they can have an emergency and no one will be around to help), and a litter box, non-tippable water dish, etc. Then just keep them in that room.
A better alternative might be to have someone take the dog home with them for the duration and let the cats have the whole house to roam in. I have friends here who went to Europe (the whole family) for a month, and they followed this advice carefully, placing the dogs with a friendly relative and leaving the cat-proofed house (all 7 rooms!) to the cats, with a neighbor to come in every day to feed and water the cats and sit an talk to them a little, and also to check the level and level of disagreeableness of the litter box. The cats were quite comfortable, althought extremely glad to see their family (even though they had some old socks lying around that belonged to different famly members), and the dogs were in the same state -- comfortable, pampered, but glad to see the family. It all worked out very well.
All this is pretty obvious, but sometimes one forgets every single potential problem that can occur without a human presence in the house. (for example, if the cats can run in the house, and if you have a stove top that uses natural gas, turn off the gas at its source. My cats seem to think it is funny to shove on the gas burner levers.)
Try to find a solution that will lead to a happy homecoming after a happy honemoon.
And congratulations in advance and best wishes for every happiness.
