Cats rarely present an injury. They present the evidence for one, days later, while you are stroking them: a scab under the chin, a patch of fur lying the wrong way, a bit of ear that has changed shape. By then whatever happened has happened, and the only useful question is whether it needs cleaning or whether it needs a vet.

For the first of those, this is a 200ML spray built around hypochlorous acid. Johnson's describe it as gentle yet powerful, intended for fast, effective wound care on cuts, scrapes and minor skin irritations. It goes on as a spray rather than needing to be dabbed on with cotton wool, which is the difference between a job that takes a second and a wrestling match. It is cleared for all cats and kittens over 12 weeks of age.

• 200ML spray bottle
• Antiseptic action from hypochlorous acid
• Intended for cuts, scrapes and minor skin irritations
• Cleared for all cats and kittens over 12 weeks of age
• Applied as a spray, not a wipe

Where this stops being the right product. It is for minor damage only. A wound that is deep, gaping, bleeding steadily, dirty, hot, swollen or smelly is a vet visit, and so is any bite from another animal, which is the kind of injury that looks like nothing on the day and does not stay that way. Johnson's publish no concentration, no ingredient list beyond hypochlorous acid and no guidance on how often to use it, so the bottle in your hand is the instruction, not this page.

Who it's for: owners of a cat who goes outside and comes back with things they did not leave with, and anyone assembling a first aid box for the house rather than shopping after the fact.
