Scruffing a cat: what the study measures, and what the “clipnose” clip is worth
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Grabbing a cat by the scruff passes for a natural gesture, “the one the mother uses”. The clip fastened onto the neck, sold under the name clipnose, relies on the same idea of a calming reflex. A study published in 2020 by Moody, Mason, Dewey and Niel in The Veterinary Record measured what these handling methods actually provoke (see the study, doi 10.1136/vr.105261). Our other guidance is gathered in the cat care and grooming section.

Three holds compared with passive handling
The protocol compares, within the same cat, each restraint method against simple passive handling: scruffing in 17 cats, placing a clip on the scruff in 16, and full-body restraint in 19 — the last serving as a negative reference, since it is already known to be aversive. The responses measured are immediate and observable: respiratory rate, ear position, pupil dilation, vocalisations.
The clip ranks alongside full-body restraint
The central result is clear-cut: no difference was detected between full-body restraint and clip restraint. In other words, the accessory meant to immobilise without stressing triggers as many negative responses as the method used as the aversive benchmark. Against passive handling, the clip significantly increased pupil dilation and vocalisations as well as defensive ear positions; compared with scruffing, it produced more pupil dilation and more vocalisations.
Scruffing: to be avoided, not banned
This is the nuance not to get backwards. In the final ranking, full-body restraint and the clip come top for negative responses, scruffing generates fewer than those two, and passive handling generates the fewest. The authors write that scruffing should be avoided where possible — a graded recommendation, not a ban. The gesture is therefore not neutral, but neither is it the equivalent of forced restraint.
What the study does not show
Sample sizes are small, 16 to 19 cats per condition, and the work was carried out under controlled conditions, by trained handlers: this is neither a living room, nor a waiting room, nor a nail trim. No cortisol assay was performed, nor any follow-up of long-term consequences: the indicators are immediate behavioural and physiological ones. Nor does the study say what to do instead when care becomes unavoidable and the animal struggles.
What this changes for everyday care
The practical lesson is that the least costly immobilisation is the one that constrains least: let the cat keep all four paws down, support rather than block, split sessions into shorter ones. An accessory that promises reflex calming does not replace that approach, and the study invites caution about it. Our guidance on trimming a cat’s claws and our article on the veterinary house call extend this point.
Frequently asked questions
Is the clipnose clip useless?
The study does not measure how well it immobilises, but how well it is tolerated: on that count, it does not differ from full-body restraint, which is known to be aversive. That is a serious argument for not choosing it by default.
Why does a kitten let itself be carried by the scruff but not an adult?
The study measures only the response of cats handled under controlled conditions and does not address maternal carrying of kittens. It establishes only that the gesture produces more negative responses than passive handling. Find all our guides on the cat hub.
