If your cat is mysteriously round despite eating like a bird at home, someone down the road is feeding her. It is always done with the best intentions, and it quietly undoes any diet, any prescription food and any attempt to work out why she has started being sick on the landing. A collar that asks politely has the conversation on your behalf.

The message is printed in white or in black depending on the colour of the collar, so it stays legible from a few feet away instead of disappearing into the background. The buckle is a quick-release clasp, which is not a cost saving but a safety requirement for a cat who climbs: it pops open under load rather than holding her by the neck on a branch or a fence panel.

• Message printed in white or black for contrast
• Adjustable from 18cm to 28.5cm

On fit, and on expectations. Fasten it so two fingers slide flat between the collar and your cat's neck. Tighter risks rubbing, looser and a front leg goes through it. Expect to lose one now and then, because a quick-release clasp is designed to let go and that is exactly the trade you want. The collar does not replace a microchip, and a determined neighbour may carry on regardless, though most people stop once they know.

Who it's for: Outdoor cats on a controlled or prescription diet, and any cat who has worked out that three houses pay better than one.
