Introduction

Are cats jealous? If you never lived with a cat you’ll likely answer no, but most cat owners say otherwise.

My cat, Chettoh (see this previous post) recently got a rival. After more than fourteen years as an only son, he now has to compete with another cat, a seventeen-year-old Siamese I inherited from my sister after she moved from a large house to a smaller apartment and couldn’t keep him any longer. Napo (short for Napoleon, like the XVIII century French emperor) is a tame, affectionate, lovely feline—quite the opposite of my Chettoh. My cat, since infancy, has always been an aloof, mistrustful little thug. This doesn’t mean I don’t love him. Quite the opposite. However, his supposed coolness quickly evaporated when he smelled the scent of another cat on his human mom (N.B.! Napo doesn’t live with Chettoh and me, yet. He’s still at my parents’ place, where my sister stored most of her discarded items – well, yes, Napo is one of them – but I visit every day to take care of him.)

When Chettoh started his jealous behavior, I wasn’t aware of it at first. He had always been a stereotypical cat, seeking human contact only when it was time for nourishment or physical warmth. Soon, however, unusual events became more and more frequent, for example: potty accidents, like using the floor instead of the litter box (previously, Chettoh had been a relatively clean and tidy cat), further aloofness coupled with being loud and demanding (Chettoh always preferred to isolate himself during most of the day, sleeping 80% of the time, but after he sensed the presence of another cat in my life, he alternated meowing obsessively for food and cuddles, with long periods of not acknowledging my existence or, if he did, avoiding eye contact.) (N.B.! Some information in this paragraph has been inspired by: Cats – PetHelpful).

However, can a cat really be jealous of a human? Or am I projecting a human behavior on what could simply be multiple signs of cat’s aging brain? As I said above, and in this previous post, Chettoh is now almost fifteen; in human terms he’s an octogenarian; definitely a senior.

In other words, does a non-human brain need a minimum level of intelligence to experience human-like feelings?

How Smart Are Cats?

What is the scientific evidence that cats are clever?

1. Cats have a brain that is about 90% similar to humans, with a complex surface folding pattern that increases the surface area and the number of nerve cells;
2. Cats also have more cortical neurons than dogs, which suggests that they have greater information-processing capacity;
3. Cats can learn observation and imitation, solve puzzles, manipulate objects, use tools, and communicate with humans using vocalizations and body language;
4. Cats can recognize their names, distinguish human facial expressions, and remember events for up to 16 hours;
5. Cats are not as social as dogs, but they can form complex relationships with other cats and humans based on mutual trust and respect;
6. Cats have different types of intelligence, such as spatial intelligence (cats with significant spatial intelligence are good at finding their way home from great distances. There are famous stories of cats who were lost or abandoned hundreds of miles from their owners’ places and successfully found their way back months or even years later). Other cats may excel at interpersonal intelligence (cats who form powerful bonds with their human parent, like the ones who mourn on their owner’s grave), intrapersonal intelligence (the hardest to measure: who knows what goes on in the mind of another sentient being, let alone a cat?), musical intelligence (my cat Chettoh, see previous posts, probably isn’t much endowed with this one, because he hates when I stream any music on my phone), and linguistic intelligence (some cats can mold their “meowing” into an astonishing variety of sounds and pitches to make themselves understood by their “dumb” humans.)

So, do cats get jealous?

Cats can experience jealousy to a certain degree. While jealousy is a complex emotion for humans, it’s a bit more simple for cats. Our feline friends live in the moment, so when we think they’re experiencing jealousy, it’s more likely they’re merely coveting something, whether it’s an object or a certain treatment. In contrast, humans feel jealous when we start to ruminate on the point of contention. Still, cat jealousy is very real.

Cats that are brought up and nurtured within a family are much more social. Their interactions far surpass the feeding and physical comfort stage. They are a part of the family, and they begin to act like any household member. Any upset to their balance can cause anger, jealousy and hurt.

There is some evidence suggesting that cats may indeed experience jealousy.

For example, cats may display aggressive or attention-seeking behaviors when they perceive a threat to their owner’s attention or affection. Cats have a highly developed sense of smell, and they can detect the presence of other cats on their owner’s clothes or body. This can trigger feelings of jealousy or insecurity in some cats, leading to changes in behavior. Some cats can become clingy or needy or intrude in your personal space when you are busy or occupied with something else. However, cats are complex creatures, and their behaviors can be influenced by various factors, including their personalities, past experiences, and overall environment. As a result, cats can show signs of jealousy in subtle or obvious ways.

Common signs of jealousy in cats.

• They are blocking access to furniture or doorways.
  Anecdotal Evidence: my cat Chettoh, even when he wasn’t competing with another cat, always tried to grab my attention, for example, lying sideways across the hallway or blocking access to the bathroom or the entrance/exit door.
• They make eye contact with a person or animal they dislike.
  No direct evidence for this. Napo, my other cat, doesn’t live in the same place as Chettoh, even though they both know about each other’s existence from the odorous clues each of them leaves on my hands and clothes;
• They rub on everything their competitor has touched.
  Chettoh has been rubbing on my ankles much more since I began caring for Napo. Also, he’s taken up the habit of jumping on the table where I’m preparing dinner not just to solicit food but to offer his head for cuddles;
• They solicit attention but then bite or scratch when petted.
  Anecdotal Evidence: this is typical Chettoh behavior. Oftentimes, my cat meows insistently, without apparent purpose. He doesn’t want food or drink, and isn’t sick either. Occasionally, he even tricks me into thinking he wants to play. However, when I approach him, if I’m slow to guess his real intentions, I may feel his inch-long fangs on my hand;
• They bite or scratch when someone tries to move them away from something they want.
  Anecdotal Evidence: Like most animals, Chettoh is interested in everything that moves because it might be prey. Whenever something falls to the ground, he jumps at full speed to check, eat, or play with it. One day, I was frantically typing on my PC. When the mouse slipped from my hand and landed under a table, I tried to retrieve it, but Chettoh beat me to it. Before I realized it, he’d bitten and scratched my left hand so hard it got infected. Although my doctor prescribed antibiotics and an anti-tetanus injection, it took me nearly a month to recover;
• They groom excessively.
  Anecdotal Evidence: Chettoh spends 80% of his time napping. The remaining 20% is divided between grooming (18%) and (2%) watching me while I’m eating or working. As is normal for healthy cats, Chettoh is quite clean. Lately, however, his grooming has turned excessive, so much so that the fur on his rear parts isn’t so thick anymore, and completely missing in some areas;
• They lose their appetite.
  Chettoh has always been a picky eater. There is no way of having him eat cheap food, as he’ll only nibble at top quality kibbles. I’ve always blamed this to his only son status. When there are several cats in a home, they usually gulp whatever they find in their bowls, for fear that a rival might eat it first. Since he’s detected Napo’s scent on myself, however, Chettoh barely touches his food.

How to prevent and temper cat jealousy.

Cat jealousy can be hard to prevent, but there are some ways to reduce the chances of triggering it or to deal with it when it happens. Here are some practical tips on how to make a cat feel more secure and happy in its environment:

1. Determine the trigger of your cat’s jealousy and try to eliminate or minimize it as much as possible. For example, if your cat is jealous of a new pet, introduce it gradually and carefully, making sure your cat doesn’t feel left out or replaced. Give your cat plenty of attention and praise when it behaves well;
2. Give your cat enough personal space and resources not to share or compete with others. If you own more than one cat, provide them multiple litter boxes, food bowls, water bowls, toys, scratching posts, beds, hiding places, etc. Make sure that each cat has its own designated area where it can feel safe and comfortable;
3. Teach your cat to accept and tolerate others using positive reinforcement techniques such as treats, toys, play, and affection;
   IMPORTANT: avoid punishing or scolding your cat for showing signs of jealousy, as this can make it more anxious and resentful. Instead, reward it for being calm and friendly around others;
4. Spending quality time with your cat daily gives them your undivided attention and love. Play with it, cuddle with it, talk to it, groom it, and make it feel special and appreciated. This will help to strengthen your bond and reduce the cat’s insecurity and jealousy.
