2. Sexual maturity. When cats reach sexual maturity, they may start to compete for mates. This can lead to aggression between male cats, and even between female cats if they are both in heat.
3. Health problems. Some health problems, such as hyperthyroidism or dental disease, can cause cats to become irritable and aggressive. If you notice any changes in your cats' behavior, it's important to take them to the vet to rule out any medical problems.
4. Stress. Stress can also trigger aggression in cats. This could be due to a number of factors, such as changes in the household routine, a new baby, or even just the stress of living in a multi-cat household.
5. Boredom. Cats who are bored may become destructive and aggressive. Make sure your cats have plenty of toys and activities to keep them entertained.
If your cats are fighting, there are a few things you can do to help stop the behavior.
* Separate the cats. If the cats are fighting, the first thing you need to do is separate them. This will help to prevent them from hurting each other.
* Identify the cause of the aggression. Once the cats are separated, you need to try to identify the cause of the aggression. This may involve talking to your vet or a cat behaviorist.
* Make changes to the environment. If the aggression is being caused by changes in the environment, such as new furniture or a new pet, you may need to make some changes to the environment to make the cats feel more secure.
* Provide plenty of enrichment. Cats who are bored may become destructive and aggressive. Make sure your cats have plenty of toys and activities to keep them entertained.
* Consult with a veterinarian or animal behaviorist. If you are unable to stop the aggression on your own, you may need to consult with a veterinarian or animal behaviorist.
