We'll be bringing our lab puppy home in about 6 weeks, when he'll be 3.5 months old. We also have two cats, and ideally I'd like all of them to sleep downstairs in the kitchen diner. I was thinking we'd get a crate for the puppy, and that I would sleep in the kitchen diner too for a while, until we've got toilet training sorted (we have a sofa bed in there). I'm now unsure about the crate, but I don't know if this plan will work without one? We will let the cats upstairs during the day, as they're used to that, but we won't let the puppy upstairs. If we have the cats upstairs at night, they can't get out as their cat flap is downstairs in the kitchen diner, and it's not a long term plan as we'd never be able to set the house alarm. It really would be best if they got used to being shut in the kitchen diner together, they'll need to do that in the day eventually too. My friend who has labs thinks they'll be fine, and we don't need a crate. She thinks the cats will just find a spot out of the puppies way, and they'll get used to each other. Am I being nieve to try this? Am I setting myself up for some very sleepless nights? I don't mind that initially, I'll be on holiday for the first two weeks, but when I'm working again, not sleeping at all is not an option! Thanks for any advice.
