Cat vision is excellent in low light and for detecting movement but sees fewer colors (mostly blues and yellows, with reds and greens appearing dull or grey) and has blurrier, less detailed vision than humans, making them nearsighted but great hunters. They see a more muted, less vibrant world, focusing on motion and brightness to navigate their environment.
While cats have remarkable night vision, they cannot see in total darkness. Contrary to popular belief, no animal, including cats, can see in absolute darkness. Vision requires at least some level of light to function, and if there is no light source at all, a cat's eyes will not be able to process images.
So we've covered the science behind how cats' eyes work, but what do they see when they look at us humans? Experts believe that cats see us as slightly clumsy, very big cats. It's thought that cats don't differentiate between cats and humans, so they think we're just like them, albeit larger and less coordinated.
The top "silent killers" in cats are Chronic Kidney Disease (CKD), often going undetected until 75% kidney failure, and Hypertension (High Blood Pressure), which damages organs without obvious signs until blindness or seizures occur, notes Muirfield Animal Hospital, Pet Health Network, www.springwoodvets.com.au, Close Veterinary Clinic, Killarney Animal Hospital, Physicians Mutual Insurance, Sykesville Veterinary Clinic, Mona Vale Veterinary Hospital, Nimbus Pet Hospital, Hill's Pet Nutrition, Covetrus North America, ASPCA Pet Insurance and PetCareRx. Other serious conditions include Hyperthyroidism, Heart Disease (like HCM), and Fatty Liver Disease (Hepatic Lipidosis).
To say "I love you" in cat language, use slow blinks, offer gentle head/cheek rubs (scent glands), let them initiate contact, provide interactive play, and simply share calm presence, mimicking their natural affection signals like grooming and trust-building.
To apologize to a cat, use a soft, calm tone, offer treats or toys, initiate slow blinking, give space if needed, and respect their boundaries for physical touch, focusing on actions and tone over words to rebuild trust and affection. Don't force interaction, as they respond to reassurance and positive experiences more than human language.
Research suggests that cats' short term memories last around 16 hours, which means they can remember recent events and react accordingly. If a cat has had a minor scare—such as a loud noise or being bumped by accident—it may remember and act skittishly for a short period.
The 3:3:3 Rule: Help Your New Cat Adjust to Their Home The 3:3:3 rule explains some general expectations for the transition process and some tips on how to support your cat through each stage: 3 days for initial acclimatization, 3 weeks for settling in, and by 3 months, they should be comfortable and at ease in their ...
Cats hate strong, pungent, or bitter smells, with citrus (lemon, orange), vinegar, and harsh cleaning chemicals (ammonia, bleach) topping the list, along with certain herbs (lavender, eucalyptus, rosemary) and spices (cinnamon, pepper) that can irritate their sensitive noses, with some being toxic if ingested. Strong odors like spoiled food, other animals' scents, or menthol are also highly disliked.
Cats do remember negative experiences, but they don't dwell on resentment the way people do. Instead, they react based on learned associations and their need for safety. With patience, consistency, and care, most cats return to positive behaviors quickly.
Cats get most annoyed by loud, sudden noises (vacuums, thunder), strong smells (citrus, vinegar), changes in routine, dirty litter boxes, and unwanted handling like being picked up or stared at, as these disrupt their sense of security and sensory balance, triggering their sensitive hearing and instincts for control and safety. Unexpected movements, unfamiliar scents, and being forced into costumes also cause significant stress and annoyance for felines.
While sometimes bothersome and uncomfortable, there are actually surprising benefits to letting your cat sleep on your chest. A cat's purr has been shown to reduce stress and be medically therapeutic for illnesses in humans.
For some kitties, the absence of the person (or people) or other animals (another cat or family pet such as a dog, rabbit, ferret or even a pig) causes them distress and anxiety.
Cats can become distressed at loud noises and flashes of light and keeping them in when it is dark can help reduce them feeling stressed. During this time, keep your cat flaps, windows and doors closed and ensure any unsuitable areas are blocked off.
Cats stare because they're hungry, showing affection, hunting, curious, or displaying dominance over other cats. Cats can see and hear much better than humans, so they may stare at things that we can't detect. If you notice tearing, discharge, watering, or redness in your cat's eyes, take them to the vet.
Cats have better night vision than dogs and can see things in detail as far as 200 feet away. Felines are a little better than dogs at focusing in on objects up close, but not by much.
Put down chicken wire - cats hate walking on it.
Some of the most dangerous essential oils for cats include peppermint, tea tree oil, and clove oil. Eucalyptus and cats are also a bad mix. Signs of essential oil poisoning in cats include: Drooling.
Reasons cats hate dogs
For example, a dog's wagging tail is universally seen as a sign of friendliness and fun. But cats can view it as a sign of aggression or agitation. Another example is a dog's ears. Dogs can flap their ears and pin them back when they're scared, while cats see it as aggression.
Cats can experience stress and confusion during a rehome, especially if the change is sudden. But sadness, as we experience it, isn't quite the same for cats, and they usually settle once they feel safe.
Black Cats and Dogs Have Lower Adoption Rates
Research verifies that black dogs and cats have a lower chance of being adopted. It's a tragic fact that they tend to stay in shelters longer and are more likely to be euthanized due to shelter overcrowding than animals of other colors.

The short answer is no, cats can't hold grudges. Cats don't have or process emotions the way that humans do. If you're wondering if cats have a sense of time or a concept of time, they don't. They don't have the time or mental capacity to plot revenge, get jealous, or let a grudge fester.
Cats can detect changes in the human body, such as fluctuations in sugar levels, hormonal imbalances or inflammation, which are imperceptible to the human nose but very noticeable to cats. Cats not only detect these changes, but often respond to them by alerting their owners to potential health problems.
