Do Cats Get Jealous?

There are many people who assume that jealousy is uniquely human, but the same exclusivity was thought to be true about others traits that have since been found in other animals: tool use, language, abstract thought, art, personality, humour, music and grief, to name but a few. 

Jealousy is an emotion that evolved to protect social relationships from intrusion by outsiders to those relationships. So, it is likely to exist in many animals who value social connection, including cats. So, do cats get jealous? It’s hard to imagine they don’t.

Do cats experience jealousy?

Research about jealousy in animals is not common, and even the work that is published on the subject focuses on behaviours, rather than the emotion itself. So, if the goal is to know whether cats experience jealousy like humans, or just exhibit behaviours consistent with jealousy, we really don’t have the answer.

The same is true when we observe people who we ‘know’ are jealous. The observations we make are based on behaviour as well as expressions related to sadness, anger, anxiety and fear. The anxiety causes a monitoring of the situation, and the other negative emotions result in attempts to protect the relationship. That monitoring and those attempts are the behaviours we see when we observe cats acting (and presumably feeling) jealous.

We lack the research, but with behaviours similar to those expressed by humans who are jealous, it is reasonable to assume that cats do experience the complex emotion of jealousy.

What are some signs that a cat may be exhibiting jealousy?

Because it is not always possible to know for certain how a cat is feeling, it is smart to pay attention to their behaviour and think about how that may provide clues to their emotions. With jealousy in mind, behavioural clues that they are experiencing that emotion can be any action that attempts to monopolise someone or get rid of any competitors for affection, attention and resources. 

One of the most common signs of jealousy in cats is acting possessive of their pet parents or of other members of the household. That can be a dog, another cat, a rabbit, a child, or anyone else they like to be social with. Sometimes that possessiveness involves acting aggressively towards other animals or to people. The aggression can simply be threats or can involve scratching and biting, too. Some jealous cats never behave aggressively, but others are so upset by their big feelings they cause harm. Many cats seek extra attention by approaching more frequently, rubbing against you, or lying down in a spot right in front of you or on top of what you are working on.

It takes some patience (shocker), but it can be done

Other behaviours that may indicate your cat has a green-eyed monster lurking within could be anything that suggests they’re upset or stressed. Being upset by jealousy can result in a variety of behaviours. Destructive behaviour may pop up with cats clawing at things or knocking them over. Excessive vocalising is another sign of a cat who is upset or stressed, so some jealous cats may act in this way. Other cats react to negative emotions by hiding or being evasive, so if your cat sneaks off or avoids other members of the household, those actions can also be clues that a cat is feeling jealous. Some cats who are upset will groom excessively, so this change can be a useful barometer of your cat’s emotional state.

What are common triggers for jealousy in cats?

Any change to their routine that results in them receiving less of something they enjoy can trigger jealousy. They can also be upset by another member of the household receiving good things such as food, treats, attention and playtime, which can all result from various events. Adopting a new pet into the household can leave a resident cat feeling jealous; if a pet parent is preoccupied, extra busy with work, giving more attention to another pet or begins a relationship with a new person, a cat can become jealous; if a change in routine results in less attention from people in the household, or their cat buddy becomes BFFs with the new dog, a jealous cat may be the fallout from that change. 

Could underlying health issues contribute to jealous behaviours in cats?

If cats have health issues that limit their access to certain areas of the house, the result can be jealousy. For example, if an injured or older cat becomes unable to jump up on the bed but other pets are up there for hours enjoying affection from the people binge watching Ted Lasso, for example, the cat who is left out is certainly likely to feel jealous. If they are too overweight for a certain perch to support them, but another cat is on it, jealousy is understandable. So, if health issues mean they can’t access certain areas to get attention or can’t physically participate in socialising, those health issues could indeed contribute.

How can I manage or prevent jealousy in my cat?

To prevent and manage feline jealousy, focus on making sure your cat is getting enough attention, playtime, treats and toys. Provide them with additional cosy perches or good spots to sleep if they are acting jealous or if an impending change is coming. If there has been a big change, such as a baby or a new pet, they may need even more expressions of love from you than before because they may be hyper-aware they have to share you now, and not every cat likes that or is able to cope well. 

It helps to introduce new pets or people slowly and gradually and to do all you can to make the introductions positive. You want your cat to associate any changes with good things and attention in the form of treats, petting and playtime rather than associating changes with a decline in life’s pleasures. It always helps to be patient, empathetic and understanding with your cat. It can be hard for them to adjust to big changes, and the more you attend to their needs and focus on them, the easier it will be to manage and prevent jealousy in your cat.

Can professional behaviour modification techniques help with jealous behaviours in cats?
