Why does your cat sleep on your clothes? The sweet reason your scent may make them feel safe

Have you ever left a pile of clothes on the bed or chair, only to find your cat curled up comfortably on top of them? It may look like your pet has simply chosen the softest place for a nap, but there could be another reason behind this adorable habit. Cats have a highly developed sense of smell and rely heavily on familiar scents to understand their surroundings. That means your unwashed T-shirt, sweater or blanket may carry something your cat finds particularly reassuring: your familiar scent. A recent study published in PLOS One found that domestic cats spent substantially more time sniffing the odour of an unfamiliar person than that of their owner, suggesting that cats can distinguish between familiar and unfamiliar human odours.




For cats, scent is an important part of understanding whether an environment feels familiar and safe. Cats Protection advises owners to leave an unwashed item of clothing with a cat when it is adjusting to a new environment because the owner's familiar scent can help the animal settle. This may help explain why your cat chooses your clothes when you are not around. A shirt that smells like you can provide a familiar sensory cue in an otherwise quiet environment. It does not necessarily mean your cat is consciously thinking about you in the same way a human would. Instead, the scent may be associated with a person, place and routine that the cat knows well. Cats Protection also explains that cats use scent as part of their communication and may rub their faces against objects to leave pheromones. These scent cues can help make an area feel familiar and secure.





There is another simple explanation: your clothes may just be comfortable. Cats often choose soft, warm surfaces such as blankets, bedding and clothing for sleeping. Cats Protection notes that clothing can provide a comfortable resting place and that some fabrics are also suitable for kneading, another behaviour that many cats find comforting. So if your cat repeatedly chooses your laundry, several factors may be working together. The fabric may be soft, the spot may be warm and, importantly, the clothing carries a familiar smell. This can be especially noticeable when you have been away from home. A familiar-smelling item can provide continuity while your cat is waiting for you to return. Cats Protection specifically recommends leaving clothing that smells of the owner with cats that may be stressed or unsettled by changes in their routine.




It can be a positive sign, particularly when it happens alongside other relaxed and affectionate behaviours, but it would be too strong to say that sleeping on clothing is definite proof of love. Cats communicate differently from humans, and their behaviour can have more than one explanation. A cat may sleep on your clothes because it associates your scent with safety, because the material is comfortable, or simply because that particular spot happens to be appealing. Research does show that cats can distinguish familiar human voices, and newer research suggests they can also discriminate between familiar and unfamiliar human odours.

So the next time you discover your cat sleeping peacefully on your favourite T-shirt, there may be more happening than a simple search for a comfortable bed. Your clothes carry a little piece of your familiar sensory world. For a cat that trusts you, that familiar smell may help make an ordinary piece of fabric feel like a safe place to rest. In other words, your cat may not be saying, "I miss you" in words, but choosing your clothes could be one quiet way of staying close to something familiar.
