Pheromone collar for anxious Chausie cat

A vet flagging anxiety-related weight loss is a meaningful signal — it means the stress has been significant enough to show up physically, which in cats often means it's been building quietly for a while. Chausies are high-intelligence, high-energy cats, and that mental wiring can make them more susceptible to chronic low-grade anxiety than more placid breeds. Your vet's instinct to go pheromone collar rather than diffuser makes sense here — a collar delivers the calming signal right at the source and travels with the cat, which matters for a cat whose anxiety isn't room-specific. Before I point you to the right product, can you tell me a bit more: do you have any sense of what's been triggering it — any changes at home, new animals, routine shifts? And what are you seeing day to day — hiding, reduced appetite, over-grooming?

That all makes sense together — a house move is one of the most disorienting things for a cat, and Chausies in particular are very territory-anchored. Four months of low-level stress accumulating into weight loss tells you her nervous system hasn't had a way to reset. A pheromone collar is the right call, and I'd point you specifically to the Feliway Optimum collar. It's based on the newer multi-pheromone complex rather than the original single-pheromone formula, which means it addresses a broader range of stress signals — important when the anxiety has become generalised rather than triggered by one specific thing. It lasts 30 days, sits close to her face and neck where she'll get continuous exposure, and works within a few days for most cats rather than the two-week lag you sometimes see with diffusers. For a cat hiding and not eating after a move, that faster onset matters.

Yes, meaningfully different. The original Feliway collar uses just the feline facial pheromone — the one cats deposit when they rub their face on things, which signals safety in a familiar space. The Optimum formula adds what Feliway calls the 'harmony pheromone,' which targets social and environmental stress more broadly. For a cat whose anxiety has become whole-body — affecting appetite, movement, behaviour — the Optimum is the stronger tool. It costs a little more, but given that your vet is already tracking this medically, it's worth using the version with the widest coverage. Stick with the Optimum.

Start with the collar alone. The logic for using a collar first is that you don't yet know which spaces she'll use as she slowly re-emerges — and a diffuser needs to be in the right room to be effective. The collar goes with her, so it's working wherever she is, including under the bed. If after two to three weeks she's eating better and coming out more but still seems tense in specific rooms, that's the point to add a Feliway Optimum diffuser in those areas. Layering too much at once also makes it harder to know what's actually helping. One thing at a time, collar first.

A few things that genuinely help alongside the collar: keep her feeding station, litter tray, and a resting spot in one predictable location — consistency in micro-geography is calming for cats rebuilding their mental map of a space. Don't try to coax her out from under the bed; let her emerge on her schedule, but make sure wherever she hides feels safe and undisturbed. Feliway also has a spray version you can apply to her bedding or a blanket under the bed to reinforce the effect in her retreat space. And keep vet check-ins going — given that weight loss is already documented, it's worth a weigh-in in four weeks to confirm she's stabilising. The collar should do a lot of the heavy lifting, but environment consistency is what lets it actually work.
