My cat is aggressive towards my dog. What would the vet check?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 8 years and 2 months old | 14 lbs

I’ve been advised to take my cat to the vet for a checkup because he’s been more jealous and aggressive toward my little dog. At night he will stalk her on the bed with me and I have to intervene before he attacks. He’s always been very alpha in personality but seems to have decided to act on it recently. I take very good care of my animals. I brush their teeth and feed them expensive food and play with them. I am confident this is not a health issue, I am very observant. What would vet check?

The vet could do a physical exam, blood work, and a urinalysis. It is a good recommended to take Banny into your vet for a health check when they are suddenly acting differently. It's the best way to know for sure that there isn't an underlying health problem, and behavior changes are often the first sign of a health problem in cats. When they are in pain or feeling sick, they can act aggressively. I do recommend the vet visit. Best of luck.

My 7 yr. Old indoor female cat is suddenly becoming aggressive and wanting to fight and growl at my MALE 5 yr. Old indoor cat. They both are up to date with their shots! She almost acts as if she doesn't know him.
Something is probably going on with her, she is possibly ill or in pain and that may be causing her to be aggressive. i would recommend taking her to the vet for a checkup and blood test to make sure she is in good health first.

My cat has gotten very violent lately for no reason, what could be the problem?
Any sudden change in behavior warrants an exam with your veterinarian. Frequently, illness or injury can be the cause. It may also be some redirected aggression, especially if Bella can see or hear cats outside. If she is upset by them and can't get to them, she may strike out at whoever is close. Once medical causes are ruled out, check your property for signs of nearby ferals or neighborhood cats. Use a pest repellant along the border of your property. You can buy a liquid or powder at most hardware or home improvement stores. Try to limit her sight from windows or doors if possible. Try a pheromone product such as Feliway spray or diffuser to decrease any anxiety or aggression.

My 2 cats have always gotten along perfectly, until yesterday, the older one just flipped out and has been very aggressive and beating up the other cat, however when separating them the older cat that has lost the plot also Attacks us. What has cause
Oh my, that is strange that Stan has suddenly become aggressive! A sudden change in behavior from the normal can signal a medial problem. Cats who are sick or are in pain can become aggressive to other animals and their humans. I would have Stan seen by a vet today or first thing tomorrow. The vet can give him a physical exam, blood tests, a urinalysis, and possibly other tests such as an x-ray to diagnose if there is a medical illness causing his aggression. If one is found, the vet can discuss treatment with you. If one is ruled out, I will give you a method to help them get along again. I would separate the cats, and slowly reintroduce them to each other. Take Stan, and put his in his own room with his own food, water, and litter box. Keep the door closed, and for a few days, feed them both treats on other side of door so they associate each other's smell with a good experience. Then let the other cat into Stan's room while he is in a cat carrier. They can smell each othe

Hi. I have 3 cats. One I introduced 2 years after getting the first 2. The 3rd has become very withdrawn and acting aggressively, one of my older ones chases her and seemingly plays but she reacts very aggressively with hissing and retires to a hidde
Sudden aggression and behavior changes in cats can sometimes indicate pain or underlying illness. I would make sure to schedule a vet checkup to rule out any health issues that could be causing the behavior. If she checks out healthy, making sure all of the cats have their own access to food, water, litter, bedding, places to hide, etc can help decrease inter-cat tension. Spending some time with each, and giving your cat a break if she becomes too irritated or agitated may help as well. If the behavior persists or worsens, speaking with a trainer or behaviorist in person is a good next step as well.

Why is my cat suddenly aggressive? He was so sweet and only 4 days ago he was mean. He still is. I give him food, play with him do everything correct, and he is aggressive.
There are several reasons for sudden onset of aggression including pain or infection somewhere, an increased thyroid hormone, or anxiety. If you want, you can try some feliway which is feline pheromones to help calm him. If This doesn’t work or if he stops eating or starts showing any other abnormal behaviors then I would have your vet take a look at him. Your vet will be able to ensure he doesn’t have an infection and they can even check his thyroid hormones of needed. If everything is normal, then talk to your vet about putting him in an anti-anxiety meds if needed. I hope this helps!

How to deal with aggressive cat?
It would be hard to give a specific answer without more information. If your cat is being aggressive toward other cats, separating them and making sure each cat has access to their own food, water, litter, etc can help reduce tension. If your cat is being aggressive toward you, a good first step is a trip to the vet as pain or illness can sometimes cause behavioral changes in cats. If Chester checks out healthy, speaking with a veterinary behaviorist may be helpful in figuring out what is going on, and working on a combination training/medication plan to help reduce the behavior. https://www.dacvb.org/page/about

I'm so sorry to hear that Kitty seems to have a change in her behavior. I would be concerned that she may not be feeling well or potentially be in pain, causing her to be aggressive. I would recommend you take her to your veterinarian to have a full physical exam. There may be something physically wrong with her causing her to act out. If she is not spayed, I would also consider spaying her, as hormones can cause behavioral problems. If she is healthy and there is no underlying medical cause of her change in behavior, there may be something in her environment that is causing her stress. Sometimes environmental enrichment, like shelves, cat towers, etc, can help with behavior issues. Feline pheromones (Feliway) can also help some stressed cats and calm them. Finally, some cats do need to be put on behavior modification drugs, if the other previously discussed things are not the problem. You can discuss this with your veterinarian. Best of luck! I hope she is acting more frien

Gracie has become suddenly very aggressive with our male lab. She is 19 lbs and petite, he is 75 lbs and a big boy. He is submissive for the most part, but will fight back if need be. For example, he was laying on the bed and she walked over to him,
With any sudden new behavior such as aggression in normally well behaved pets, it is best to schedule a vet visit. Pain and underlying illness can sometimes lead to sudden aggression or other behavioral changes which can lead to one dog attacking another, or the dog in pain becoming overly defensive and causing fights as a way of protecting itself against the perceived pain. Having both pets checked out for any issues is a good idea. If they both check out healthy, speaking with a trainer that can observe the behavior in person (and/or taking video to show a trainer) may help figure out if there is a cause to the sudden change and what can be done to help.

Sorry you are having some troubles with Monster! I recommend that you take him to your vet for a senior blood panel. They can check his thyroid as well. Hyperthyroidism (an overactive thyroid gland) is not uncommon in older cats and can lead to behavioral changes, more vocalization, eating more, acting odd. Get him in for bloodwork when you can! Thanks for asking Boop by Petco!

Having a health check with the vet is a good idea for Abdul. Sometimes when a cat suddenly becomes aggressive, ti can be a sign that he is ill. I'd take him into the vet in the morning. If he checks out health wise, try this method below to see if it helps. Best of luck. I would separate the cats, and slowly reintroduce them to each other. Take the cat who is aggressive, and put him in his own room with his own food, water, and litter box. Keep the door closed, and for a few days, feed them both treats on other side of door so they associate each other's smell with a good experience. Then let the other cat in the aggressive cat's room while the aggressive cat is in a cat carrier. They can smell each other, but not be in contact. If either becomes upset or show signs of aggression, remove the second cat from the room, and try again later. Praise them when they interact appropriately. When they are interacting well with each other through the carrier, you can let the aggressi
