Sentry Calming Collar Good Kitty, 38 cm is a calming collar for cats of all breeds and ages, made with patented pheromone technology. The pheromones mimic those a mother cat uses to calm her kittens. Cats recognise this signal throughout their lives, so the collar has no age limits. According to the manufacturer, these pheromones are clinically proven to reduce or eliminate stress-related unwanted behaviour. The collar lasts 30 days.
How the collar works
The calming effect of the pheromones "switches on" as soon as you put the collar on. The cat's body heat helps release the pheromones gradually, so the cat is always within their range — at home, in the carrier or at the clinic. Some pets need more time before results show, depending on the individual cat or how severe the stress is. The collar can be worn continuously or on and off over the 30 days. Other ways to ease stress are covered in calming products for dogs and cats.
When it helps
The manufacturer says the collar helps change stress- and fear-related behaviour such as inappropriate marking, aggressive scratching and excessive meowing. It helps cats cope more calmly with moving or travelling, visits to the vet or shows, new animals or strangers in the home, fear of thunderstorms and fireworks, and being left home alone.

How to fit it
Adjust the length so two fingers fit comfortably under the collar, then trim off the excess. For the first few days, check for skin irritation on the neck and make sure the cat isn't catching the collar on furniture. If your cat goes outdoors or likes to climb, remove the collar during unsupervised outings. After 30 days, replace it with a new one if the stressful situation continues. For trips and vet visits, you can also treat the carrier with Feliway spray.
Collar, spray or diffuser
A collar is handy when the cat moves around a lot or the stress involves people and other animals, as the pheromones are always with it. A diffuser such as Feliway Classic creates a calm atmosphere in one area of the home, while Feliway Friends helps with conflicts between cats. If your cat is marking, also have a vet rule out urinary problems — tips in cat not using the litter tray: what to do.
Who it suits
Cats that struggle with moves, travel, visitors, new animals and loud noises, or that mark or become aggressive under stress. More products are in the medications section.
Verdict
Sentry Calming Collar Good Kitty is a convenient calming collar with mother-cat pheromones that works for 30 days and needs no socket. It suits cats of any age. The downsides are the lavender and chamomile scent, which not every cat likes, and the fact that many cats won't accept wearing a collar.
