A dog and a cat under one roof: give the cat a way out
Sharing a house is not the same as sharing a space. A cat that can leave the room whenever it wants usually copes better than one that cannot.
Give the cat height and a hiding place
Dogs Trust says to give your cat plenty of high places, like cat trees, wall shelves or raised furniture, so they can move away from the dog. Cats also like covered spaces such as a box without a door, a cave bed or a blanket over a chair. VCA agrees that your cat should have a private place to retreat to, often raised, and suggests at least as many safe spaces as cats in the home.
Let the dog have its own space too
Dogs Trust notes that many dogs feel most comfortable in open spaces, and that a puppy pen or baby gate can keep dog and cat apart without shutting the dog in a small space. A baby gate across the stairs, for example, leaves the cat free to go up to a safe space of its own. Some dogs also like a covered crate, introduced gradually with rewards.
Separate food and water
Dogs Trust recommends feeding the dog and cat separately and giving each their own water bowl, which helps prevent stress. The AKC makes a similar point for any multi-pet home: meals work better when animals eat apart.
When things do not settle
Dogs Trust suggests supervising the two and, if needed, keeping them completely apart in different rooms. If they are not getting along, it also offers a Behaviour Support Line for advice.
Keep a simple log
Jot down the date, where each pet was and how they reacted. In PawLine, dated notes for each animal make it easier to see change over time.
Questions about this guide
Does my cat need a room of its own?
Not always, but VCA says every cat should have a private retreat, often raised. Dogs Trust suggests high places or a gated floor so the cat can leave.
Is a baby gate enough?
Dogs Trust says gates and pens can keep dogs and cats apart and let them see each other in short, calm sessions. Supervise, and separate completely if needed.
