Yes, holding a cat by the neck (called “scruffing”) can cause pain, and it almost certainly causes stress and fear. While mother cats carry tiny kittens this way, the technique does not work the same on older kittens or adult cats. Both the American Association of Feline Practitioners (AAFP) and the International Society of Feline Medicine (ISFM) discourage scruffing as routine handling, and their joint guidelines explicitly state that lifting or suspending a cat’s body weight by the scruff is “unnecessary and potentially painful.”
Why Kittens Go Limp but Adults Don’t
Very young kittens have what’s called a “flexor reflex.” When a mother cat bites down on the loose skin at the back of a kitten’s neck, the kitten goes limp, tucks its legs, and relaxes its muscles. This makes the kitten easy to carry short distances without injury. It’s a survival mechanism: the mother needs to move her litter quickly, and a squirming kitten would make that dangerous.
This reflex disappears within the first few weeks of life. By the time a kitten is old enough to walk and explore on its own, its mother stops carrying it this way. An adult cat weighing 4 to 5 kilograms (roughly 9 to 11 pounds) is far too heavy for this technique to be safe or comfortable. The loose skin at the scruff was never designed to bear that kind of load.
What Scruffing Actually Does to an Adult Cat
When you grab an adult cat by the scruff, the cat may freeze. This looks like calmness, but veterinary behaviorists at Tufts University describe it as “behavioral shutdown,” a state of learned helplessness triggered by extreme fear and stress. The cat isn’t relaxing. It has essentially given up trying to escape because it feels it has no control over the situation.
Research published in Veterinary Medicine International found that scruffing increases arousal and fear in cats, compromising their sense of control and welfare. Placing clips on the scruff (a technique sometimes used in veterinary clinics) produces the same elevated stress behaviors as scruffing by hand. Cats in these situations show a cluster of recognizable anxiety signs: lip licking, excessive salivation, dilated pupils, ears flattened sideways or backward, tail tucked tight against the body, and limbs pulled underneath to make themselves appear smaller.
Among cats, scruffing happens in only three natural contexts: a mother transporting very young kittens, a male cat gripping a female during mating, and one cat asserting dominance over another in a fight. When a human scruffs a cat, the experience most closely resembles that last scenario. It signals dominance, not safety.
Physical Risks of Lifting by the Scruff
The AAFP and ISFM joint panel is clear on one point: never lift a cat so that its full body weight hangs from the scruff. Adult cats are heavy enough that this can strain the skin, underlying tissue, and neck muscles. Unlike a tiny kitten weighing a few hundred grams, an adult cat’s body creates significant downward force on a relatively small fold of skin. The guidelines call this technique potentially painful and entirely unnecessary.
Even without lifting, gripping the scruff with too much pressure can cause discomfort. “Scruffing” covers a wide range of holds, from a light pinch of skin to a firm, controlling grasp. The harder the grip and the more the cat struggles against it, the greater the risk of pain and soft tissue strain.
Long-Term Effects on Your Cat’s Behavior
Cats have excellent associative memories. A cat that is repeatedly scruffed, whether at home or during vet visits, can develop lasting negative associations with being handled. This is one reason veterinary organizations have moved away from scruffing: it conditions cats to react defensively to human hands near their neck and head, making future handling progressively harder.
Cats that feel they’ve lost control in a situation tend to escalate their defensive responses over time. A cat that freezes the first time it’s scruffed may bite or scratch the next time, not because it’s become “meaner,” but because it’s learned that freezing didn’t keep it safe. This cycle of fear and escalation is well-documented in feline behavioral research, and scruffing is a common trigger.
How to Handle a Cat Safely Instead
The simplest approach for everyday handling is to support your cat’s full body weight at all times. Place one hand under the chest just behind the front legs, and use your other hand or forearm to support the hindquarters. This keeps the cat stable and gives it some sense of control, which is the single most important factor in reducing feline stress during handling.
For situations where you need to restrain a cat (giving medication, trimming nails, or managing an anxious cat), a towel wrap works well. Place a towel lengthwise on a flat surface, set your cat about two-thirds of the way along it facing away from you, and fold the shorter end over the cat’s body, tucking it underneath. Then wrap the longer end around and over, tucking it snugly so only the cat’s head is exposed. If you need access to one paw for nail trimming, you can extend a single leg outside the wrap. Some cats actually calm down more when the towel covers their head, giving them the sensation of hiding.
If your cat is in a true emergency, panicking, or about to escape into a dangerous situation, a brief scruff hold with your other hand supporting the cat’s weight from below is considered acceptable by some veterinarians as a last resort. But even then, the goal is control for a few seconds, not lifting. Watch for signs of escalating fear: flattened ears, dilated pupils, a tightly wrapped tail. If the cat shows these signs, it’s under significant stress and the hold should end as quickly as possible.
