Yes, unneutered (intact) male cats are generally more aggressive, especially towards other males, due to higher testosterone levels driving territorial behavior, fighting, and mating urges, but unspayed females also experience hormonal aggression during heat cycles, making neutering/spaying crucial for reducing overall aggression in both sexes.
Aggression: Male cats that have not been neutered can exhibit more aggressive behavior than their neutered counterparts, driving them to get into fights with other toms, which can lead to injury.
Post-neutering, cats typically show reduced aggression within 2 to 4 weeks as hormone levels stabilize. Symptoms include decreased fighting, marking, and dominance behaviors. Neutering lowers testosterone, reducing territoriality and aggression.
Animal specialists say that if you do not neuter your male pets, their testosterone levels will keep rising. When this happens, aggression usually takes over and this can be dangerous. Intact male pets will start fights with other male pets. People can take the brunt of this aggression as well.
Understanding Aggression in Unspayed Cats
The fluctuation of hormones, particularly estrogen and progesterone, can lead to increased territoriality, irritability, and a higher likelihood of engaging in fights with other cats.

Reduced Aggression and Calmer Temperament
One of the most noticeable spayed female cat behavior changes is a calmer demeanor. Female cats that were previously irritable or aggressive may become more relaxed after spaying. This happens because hormonal fluctuations associated with heat cycles are eliminated.
Neutering is the top consideration for cat welfare. Cats can reproduce from an early age and are capable of having several litters a year. Large number of cats in an area usually result in poor cat welfare because of disease, malnutrition or cruelty.
Cat behavior red flags signal potential medical or emotional issues, including sudden changes in eating/drinking, litter box problems, excessive vocalization, increased hiding, aggression, lethargy, or changes in grooming (like overgrooming or stopping). Because cats hide illness well, any significant deviation from their normal routine, such as increased thirst, appetite changes, or unusual hiding, warrants an urgent vet visit to rule out serious underlying conditions like kidney disease, hyperthyroidism, diabetes, or pain.
Keep in mind that a number of medical conditions can cause or contribute to your cat's aggression, including toxoplasmosis, hyperthyroidism, epilepsy, abscesses, arthritis, dental disease, rabies, trauma, and sensory decline or cognitive dysfunction in older cats.
A whistle or other loud noisemaker may do the trick, as long as they're used immediately. It also helps to understand what's causing the aggression. Your cat may not like being petted or may feel territorial after the arrival of a new feline in the home. Assess these environmental factors as well.
Some of the signs that your cat is masturbating, or has the intention to include:
Neutered cats are more 'homebodies' and may eat much more, in addition to having a slightly reduced metabolic rate. This means that, combined with less energy expenditure from no longer roaming and looking for mates, some cats may put on weight.
Taylor Swift's cats, Meredith Grey and Olivia Benson, are Scottish Folds, known for their folded ears, while her third cat, Benjamin Button, is a Ragdoll, a large, fluffy breed. The Scottish Fold's ear fold comes from a genetic mutation causing cartilage issues, leading to health concerns like arthritis, prompting animal welfare experts to urge caution with the breed despite their popularity.
Male cats who are neutered are less likely to fight and defend their territories. Diseases are less likely to be spread, and fewer injuries will happen because they aren't fighting, which leads to much happier and healthier male cats.
Friendliest Cat Breeds
Any type of physical punishment can increase a cat's fear or anxiety and worsen aggression. Medications may help, but only in combination with behavioral and/or environmental modification. Recognizing aggression and startling an aggressive cat without physical contact is usually effective.
House soiling in cats, also called feline inappropriate elimination, is the most common behavioral complaint of cat owners. Problem behaviors can be urine and/or stool deposited outside of the litter box, or marking behaviors.
Signs of conflict between cats can be open or silent. Signs of open conflict are easy to recognize; the cats may stalk each other, hiss, and turn sideways with legs straight and hair standing on end up to make themselves look larger. If neither backs down, the displays may increase to swatting, wrestling, and biting.
It's never too late to neuter a cat. While the surgery may be slightly more complex in older animals (due to larger organs, more fat, and potentially higher anesthesia risks if underlying health conditions exist), the health benefits, especially reducing the risk of cancers and infections, are still profound.
Spaying and neutering are routine, affordable surgeries that can prevent thousands of animals from being born, only to suffer and struggle to survive on the streets, be abused by cruel or neglectful people, or be euthanized in animal shelters for lack of a loving home.
They are also more likely to become aggressive toward other cats, dogs, and people in the home. Un-neutered male cats are at risk of prostate and testicular cancer.
For cats: It is generally considered safe for kittens as young as eight weeks old to be spayed or neutered. To potentially avoid the start of urine spraying and eliminate the chance for pregnancy, it's advisable to schedule the surgery before your cat reaches five months of age.
More Affectionate (or Consistently So): While a cat's core personality remains intact, many spayed cats become more consistently affectionate or even more cuddly, as they are no longer distracted by reproductive urges. Their focus can shift more towards their human companions.
Senior cats may act aggressively in old age because their patience has declined over the years, and they're less and less tolerant of any changes to their routines. It may also stem from the senior cat feeling unwell, so they act out of some form of pain.
