Kitten separation anxiety: calming help for pairs

Two 7-week-old kittens adopted together — that's actually a lovely setup, but it does mean they've become each other's entire world very quickly, which can make even brief separations feel enormous to them at this age. Cat anxiety is real and often underestimated; cats hide stress well, so by the time you're seeing obvious signs, it's worth taking seriously. Pheromone products are the most effective calming option, but they need to be placed correctly to work. Before I point you in the right direction — what are you actually seeing when they're apart, and are the separations happening for a specific reason, like vet visits or separate feeding?

That makes complete sense — the smaller kitten has likely built more of its sense of security around its sibling, so even a short separation feels like a real threat at this age. The crying and door-scratching are classic stress responses, not just protest behaviour. Before I recommend anything, a quick question: are they sleeping together, eating in the same space most of the time, and roughly how long have you had them?

Got it — two weeks in, deeply bonded, and the separation for meals is brand new to them. This is a very specific situation and the right product here is the Feliway Friends diffuser. Feliway Friends uses a synthetic version of the cat appeasing pheromone — the one mother cats produce to comfort their kittens — which is different from the standard Feliway Classic. For bonded pairs, Friends is the correct formulation. Plug it in the room where they spend most of their time together, not the room you separate them into. It works by reducing the baseline anxiety between interactions, so the separations feel less destabilising over time. It takes a few days to build up, but most owners with bonded kittens this age see a real difference within a week. You can find it easily on Amazon UK — just search Feliway Friends diffuser starter kit.

Yes, it's safe — Feliway Friends is pheromone-based, not a sedative or medication, so it has no pharmacological effect. It's essentially mimicking a natural signal kittens have been responding to since birth. There's nothing in it that interacts with their developing systems. The only thing I'd say at seven weeks is that if the smaller kitten continues to struggle with feeding competition as they grow, it's worth mentioning to your vet at their first check-up, just to make sure there's no underlying health factor slowing them down. But for the anxiety itself during brief separations, Feliway Friends is exactly the right tool.

One diffuser covers up to 70 square metres, so for a standard flat it's usually sufficient — place it in the room they use most, typically wherever they sleep. If your flat is open-plan and large, you might eventually want a second in a secondary space, but start with one in their main room and see how they respond. The starter kit comes with 30 days of refill included, which gives you enough time to assess whether it's working before you commit to refills.
