Furry Jealousy: More Than Meets The Eye

Challenging behavior taking place under your roof? Is one pet launching itself at another unprovoked?

Many pet owners like yourself find themselves in a similar conundrum, trying to decipher if their pet's unusual - even hostile - interactions towards fellow pets, newborns, or even newcomers in the household point to jealousy.

Let's get into the complex dynamics of this intriguing emotion as it could be perceived in the context of your cat's behavior.

But remember, our goal extends beyond mere understanding. We aim to provide actionable advice to ease your cat's discomfort and curtail any aggressive behavior.

What is jealousy in cats?

"Did Kitty pee on the bed because she's jealous of my new boyfriend?"

"Does my cat attack my other cat because he's jealous of her?"

"Does my cat hiss at my new baby because she's jealous?"

What is jealousy anyway?

Jealousy is common in humans, and we all experience it from time to time.

It's often defined as a hostile emotion over a perceived advantage someone else has.

Is jealousy always a bad thing? Not necessarily. In some cases it can be a good thing: Jealousy can motivate us to work harder.

However, jealousy is also known as "the green-eyed monster" because it can make people do horrible things. It's certainly a complex experience for humans, involving a slew of conflicting emotions and thoughts.

The feline world is a much simpler one.

Cats definitely don't experience jealousy in the human sense of the word. That said, negative behaviors, often aggressive ones, can be associated with a certain member of the cat's household (human or animal).

When we also perceive an advantage that a family member has over the cat in question, we may interpret the behavior as jealousy.

So do cats actually get jealous?

Sometimes the cat's behavior is indeed caused by competing over resources such as territory, food or the owner's affection. When that is the case, you could say - at a stretch! - that the cat is jealous.

Other times, the cat is actually stressed over a change. Whatever has changed in Kitty's surroundings scares her or him, leading to fear-induced aggression.

We may be able to pinpoint the change to a newly adopted cat, a baby, or a new boyfriend, but that doesn't mean the cat is jealous of them. It's more likely that Kitty just needs help with adjusting to the new situation.

Situations where cats appear to be jealous - and what to do about it

Let's take a look at the common scenarios people ask about.

Is my cat jealous of my other cat?

But what about cats who are already living together peacefully, only for one of them to start attacking the other? This is when many owners bring up jealousy as an explanation. The attacker must be jealous because the other cat is getting more attention, right?

Probably not. What you're seeing may very well be a struggle for dominance. Cats have a hierarchy between them, and that "pecking order" can sometimes change, for any number of reasons. The way for a dominant cat to implement a "new world order" is by mock-attacking - and sometimes just attacking - the other cat.

There can be other reasons for sudden aggression. The attacking cat may be in pain, ill, or just stressed over something else. In that case, his or her "sibling" may be on the receiving end of redirected aggression.

What to do?

If one of your cats becomes aggressive to another resident cat, first rule out any medical problem. Look for these signs that your cat may be in pain, and if you suspect a health problem, call your veterinarian.

If the aggressor is healthy, try not to intervene. Most of these attacks are safe - even if loud! - "cat talk" that should be allowed to take place. The cats need to decide on their social hierarchy, and you have no vote on the matter.

When they're interacting, avoid reprimanding them and never shout or punish any cat in any way. If you do, they may associate the negative experience with each other, creating more problems down the road.

What you can do is make sure you offer enough resources for them to share. They should not have to compete over space, food, or water. Make sure there are enough litterboxes (one for each cat and then another one for good measure).

Provide enough food dishes (one per cat) and let them decide who uses which dish. Invest in more space by creating cat-friendly vertical space in your home. In short, minimize potential friction and let the cats work out their differences.

Is my cat jealous of the dog?

Does Fluffy attack Fido? If you've recently introduced a dog - particularly a small one - to your household, your cat is likely to try and fight off the intruder. That's not jealousy per se.

The cat doesn't really care about you bonding with the dog - he or she just wants that noisy stranger out of there.

If the two pets were not properly introduced, that animosity can carry on for years. With some cats, even proper introductions won't help much, and you'll just have to accept some level of antagonism.

If the dog and cat had been getting along just fine and the cat suddenly becomes aggressive, suspect a medical condition and check to see if there are other symptoms. Any form of sudden aggression in a cat calls for a proper veterinary evaluation.

What to do?

Taking the time to Cat trees and other measures to create vertical space are ideal for that.

Is my cat jealous of my boyfriend/girlfriend?

There are many ways in which a cat can show dislike towards a human. The cat may try to attack your new life partner or possibly just slink away.

Either way, this is probably something other than jealousy. Your cat is likely afraid of the newcomer. This could be because of a previous negative experience with that person or possibly a history of abuse by a different person of the same gender.

What to do?

Be very patient with your cat. Ask the person in question not to approach the cat or initiate any interaction - including eye contact. Let them spend time in the same room as the cat, just sitting on the floor, reading a book, and being quiet.

With time, the cat will learn that this new person is not a threat and may approach them. When that happens, have your boyfriend/girlfriend offer treats and engage in interactive play sessions with the cat. Patience is key here - this will be a slow and gradual process!

If your cat is timid or shy, check out these tips. They can help your significant other understand your cat and offer ways for him or her to be Kitty's new hero.

Is my cat jealous of my new baby?

The birth of a new baby can really affect Kitty's life. Your home is filled with new scents as well as noises (some very shrill!), and everyone's schedule is disrupted. These changes can be stressful for your cat.

Cats rarely attack babies though. Newborns are just too small and passive for a cat to see as a threat. Instead, owners may see stress-related behaviors. Your cat may pee outside the box, become more vocal or spend her or his days in hiding. That's not jealousy - that's simply stress.

What to do?

Discover how to deal with stress in cats.

My cat peed on... - is he jealous of...?

We mentioned peeing outside the litterbox earlier, but it's worth elaborating on.

When a cat pees on an object, or in a certain area, it can be tempting to assume Kitty is doing it out of spite or motivated by jealousy.

"Cat peed on my boyfriend's shoes? She must be jealous of him!"
"Cat peed in the nursery? He must be jealous of the new baby!"
"Cat peed on my bed? She must be jealous of the new cat who's sleeping there."

Sorry to disappoint, but cats are not that manipulative.

Peeing outside the litterbox can be for any number of reasons, but taking revenge on a person is not one of them.

In many cases, there is a medical explanation behind the inappropriate elimination, and that problem can be difficult to diagnose. Problems with how the litterbox is set up can also be at the root of the problem, as can overall stress. Very often it's a combination.

Sounds tricky? It can be. If you're dealing with a litterbox avoidance problem, check out this article: How To Solve Litterbox Problems In Cats: The Ultimate Guide

Final Considerations And Practical Advice

It's crucial to remember that aggression and unusual behavior can be indicative of underlying health issues. If you notice sudden changes in your cat's behavior towards other pets or humans, it might be time for a check-up with the vet.

Ensure that your home environment caters to your feline's needs. Providing enough resources like litterboxes, food dishes, and space can help minimize potential friction and reduce aggressive or distressful behaviors. Patience and gradual introduction of changes are key.

Understanding and interpreting your cat's behavior can be a challenge, but remember, you're not alone! You can always reach out to our Cat Behavior Forum, where a community of fellow cat owners and experts is ready to share advice and support.

In conclusion, the journey of pet ownership is an exciting adventure of mutual understanding and bond strengthening. By taking the time to understand your cat's behaviors and needs, you're one step closer to creating a harmonious, happy home for your furry companion.

I have a 4 girl named Baby she has suddenly turned jealous and hisses and growls at my sweet son Mikey a 6-month-old baby boy he is so sweet and just loves Being around our 4-year-old Baby. She chases Mikey out of the bedroom and out of the perch. Also now she snaps at my hubby and myself this just started last night. Mikey wants just to be friends. He loves hanging out with Baby and my hubby in his man cave. Here lately Baby is just acting like a meany and a Brat. She never used to be this way when my son Brett and daughter Gracie were alive. Could be that she still grieving for him. We have plenty of room, There is no reason that Baby should do this at all. She has plenty of space for her own food and water dish, and litter boxes We have a big house. So that is not the issue. As soon as I can, I am going to be getting Pet Remedy wipes and two starter kits for calming. Also looking at Zelekeen for Baby. I don't yell at her or scold her just tell her she does not need to be a meany and a Brat. If that is not work a trip to the vet to get some antidepressants or Anxiety medicine. She could be suffering from a depressive anxiety disorder or PTSD. She is treated like a true Princess.

we lost two cats this summer--and, for one day, Shadow, almost 4, was a "single" cat--circumstances prevailed and we adopted a male kitten, now 6 months. old. Simba is loving and sweet; however, he pounces on Shadow--and, at times, this turns into a tussle--and, Simba will chase Shadow. He is scheduled for his "surgery" Jan. 3rd. I am in hopes this will settle him down--I have tried NOT to use the spray bottle or scold him--and, he hovers. I love him and pray it does not come to the point of re-homing him. He was found walking on the side of a busy road--had a broken paw--which has completely healed. Your suggestions are awesome--thank you. I cry every time I think of him leaving our family. I only ask that he and his sister can at least be civil to one another.

I brought my female cat in our home a few months after we took in our male cat. They were rescued from under our home and it is believed that they are siblings. The male cat has shown what I believe to be jealousy even though they both are given even love and attention. He gets her down and beats her terribly, I intervene with a spray bottle and but him in one of our bathrooms for 30 minutes at a time. I can tell she is hurt from the beatings as he bites and claws her and she sadly meows loudly and shows pain where he claws and bites. He is also spraying throughout our home. I hate to do it but I want a peaceful household again and have decided to put him on a low dose of Prozac, 5 mg. 1 a day, suggested by my Veterinarian. Can anyone suggest what I could try besides what I am doing?

    If your male cat is not fixed, but is of age to be, do it ASAP. The spraying around the house is a clue. Your female is not in "the mood" and while she cannot avoid the male cat's advances, is being badly hurt by them-both physically and emotionally. If she hasn't been, she needs to be fixed as well. Many years ago we had adopted a brother and sister kittens and this behavior was the lead to get them both "repared". Afterwards, peace (such as that between siblings) ensued.

Thanking you for this educational and informative article. Our most recent addition to the furmily is 10 (adopted at 9) and has been an "only cat" prior to joining our now 3-cat family. He did spend some time living with another cat, and also lived with a dog. Joining our two girl cats, both of whom are older than he is, he gets along well with one but seems jealous of the other. He'll chase her under the bed and he tries to eat her food and use her litterbox. There are 7 litterboxes total, for three cats (because of having been a larger furmily in the past), and this is a large house (10 rooms) with lots of human and cat furniture. We're working on the issue, and it improves from time to time, though Elvis may never completely accept the fact that Baby Su lives here, lived here before him, and is also very much loved! :sigh:
It sounds to me like Elvis sees Baby Su as entertainment. Maybe some more play time with Elvis is in order. He is descended from a long legacy of hunters so the prey drive is high and as a young cat, his pent-up energy is boundless.

Three of my four are jealous of attention when I give attention to any of the other cats. They will immediately try and get between me and the cat I am giving attention to at the time. They will shove the other cat out of the way - not aggressively, they'll actually rub against the other cat as they're trying to rub against my hand for me to pet them instead, and they're so insistent about it that it pushes the other one out of the way (or rather it annoys the other one enough that they move out of the way). lol They can actually be in another room and if they hear me talking to one of the other cats they'll come running to intervene. Like "Oh no, you better not be giving them attention instead of me!"

I have an 11 and 9 year old. I moved into a smaller studio apartment 2 months ago and they are STILL fighting from time to time. I HAVE TO intervene because they get into a death grip lock and bunny kick each other till patches of fur are all over the place! Its too serious for me NOT to do anything. I've done everything from getting them more place to hide in and vertical places to climb but it just seems like they'll never get along. I'm actually thinking of giving one or the other up. Hopefully I can find a good home for one of them.

This is a funny story of what I call jealousy - I don't know what else you could call it! My husband had a cat when we met. When I moved in, I kind of became her favorite person. One morning I was ironing a shirt to wear to work. Gloves sat patiently in the doorway watching me the entire time. I took the blouse off the ironing board and laid it on the bed while I finished putting on my makeup. No sooner had I turned my back, Gloves jumped up on the bed and peed all over my blouse. She had never eliminated inappopriately before and never did it again. That, my friends, was a jealous act!
That is so funny! *Obviously not, to you, when it happened. But so eloquent on Gloves' part!*
