It can be stressful for any pet owner when their animal friend becomes aggressive, but it can be particularly confusing for reptile owners who are having trouble interpreting their pet’s behavior. If your chameleon has been changing color, hissing, or even biting whenever you come near its cage, it’s time to figure out exactly what is going on to cause this aggressive activity.
So why is my chameleon aggressive? Typically, aggressive behaviors such as hissing and biting are a result of feeling stressed or threatened. Aggression can also be the result of illness or injury, or a way of claiming territory.
In this article, we’ll explain the different causes of aggression in chameleons, as well as some methods to decrease aggression over time and make handling go more smoothly. You’ll also learn some ways to make your chameleon feel safe and secure in its environment.
Causes of Aggression in Chameleons
There are a few reasons why you may notice your pet chameleon acting more aggressively. From stress to illness to feeling territorial, we give you all the details below.
The top reason for aggression is stress. Chameleons are solitary creatures that prefer to be left alone. Because of this, any interaction–whether it’s with another chameleon, a different animal, or a human–can be very intimidating for them. If you’ve handled your chameleon from a young age, it’s more likely to be comfortable with you. If not, it’s still possible to grow trust over time.
Hissing is a common behavior that indicates stress. It’s a way to tell you to back off and give your chameleon some space. It’s definitely best to heed this warning, or your pet may bite as a defensive mechanism. Chameleons are very shy and cautious, so even a quick movement can stress them out and put them on edge.
Aside from handling, a few other sources of stress include:
- Living with another chameleon in the same enclosure
- Loud noises
- Lots of movement outside the enclosure
- Changes in environment
- Inappropriate temperatures
To end the stress and aggression, it’s important to figure out why your chameleon is stressed and address the issue. If stress doesn’t seem to be the reason for aggression, other explanations are that your chameleon is dealing with a health issue or is claiming its territory.
Illness or Injury
Chameleons are very susceptible to parasites. Viral, fungal, and bacterial infections are relatively common as well. Additional symptoms of illness are change in color, weight loss and lack of appetite, sunken eyes, and lethargy.
As far as injuries, the most common are eye infections or problems with the feet and toes. Illness and injury can cause aggression because of the discomfort your chameleon is in. This discomfort can cause it to act out, especially if you try to handle your pet.
The best way to prevent illness is to keep your chameleon’s enclosure clean at all times. Don’t leave any uneaten prey in the cage, and prevent your chameleon from coming into contact with any other animals that could spread bacteria.
Along with parasites and various infections, chameleons are also very sensitive to toxins in the environment such as household cleaners and aerosol sprays. Because of this, it’s essential to keep your pet’s enclosure in an area that’s free of any contaminants. You’ll also want to make sure to always wash your hands before and after handling your chameleon.
If you believe that illness is the cause of your chameleon’s aggression, take it to the vet as soon as you can! You’ll be able to get a diagnosis and professional advice as to how to nurse your pet back to health.
Oftentimes when another animal or a human comes close to their enclosure, chameleons will respond by changing color, lunging, and hissing. This is their way of claiming their territory and showing others that the area belongs to them. It’s very normal for chameleons to be territorial due to their solitary nature.
If your chameleon seems to be defending its territory every time you attempt to handle it, this is a sign that your pet doesn’t yet trust you or feel comfortable with you. Be patient and don’t expect to see changes overnight. It’s possible to build up the comfort level between yourself and your pet, but it’s definitely a process, especially if your chameleon is an adult that’s not used to being handled.
How to Handle an Aggressive Chameleon
First, if your chameleon bites you, don’t worry! A chameleon’s bite typically does very little damage and rarely breaks the skin. Instead, it will likely feel like a small pinch and may leave behind a bite mark.
Make sure to thoroughly wash the wound to prevent any bacteria from spreading, and then take a look at your chameleon’s jaw to make sure it wasn’t injured. If it was, it’s time for a trip to the vet.
There are a couple of methods you can use to gradually make your aggressive chameleon feel more comfortable being handled by you. One method is to purchase a sturdy plant and other perch and put it outside in the sun. Build a routine in which you take your chameleon outside to its new perch a couple of times a day.
Initially, if your pet is extremely aggressive, you may have to build up to going outside multiple times daily. You may have to start by only taking it outdoors every few days. Regardless, after this routine has been implemented, your chameleon will begin to associate you with going outdoors, and it will feel more positively toward you.
Another way to help your pet feel more relaxed and comfortable around you is to hand-feed it. Place some crickets in a small cup and hold it so that your chameleon can easily see the cup’s contents.
Your pet should quickly approach the food and shoot out his tongue in order to eat. Before long, if you keep repeating this behavior, your chameleon will begin to associate your hands with food rather than danger.
How to Help Your Aggressive Chameleon Feel Calm
Here are a few suggestions to make your chameleon feel more calm and safe in its environment. Following this guide should help to decrease aggressive behavior.
Keep Your Chameleon’s Enclosure in a Quiet Room
It’s best to set up your pet’s enclosure in a room that isn’t constantly in use. For example, you wouldn’t want to put your chameleon’s enclosure near the area where the family congregates to watch TV or eat meals. A room that is often undisturbed or that is usually quiet is the best location. A busy or loud environment can be a huge source of stress for chameleons.
Give Them a Chance to Climb
Your chameleon’s enclosure should be taller than you, with branches and accessories that allow your pet to climb up above your head. If your chameleon is able to look down from a higher vantage point, this will make them feel much less threatened than if you were looking down at them.
Provide Plenty of Plants
It’s important to keep at least three or four plants in your pet’s enclosure. The more foliage, the safer your chameleon will feel. Try to avoid making the enclosure too dark, but you do want to provide plenty of hiding places where your pet can go to feel more secure.
Avoid Fast Movements
Any quick movements will immediately be perceived as a threat or potential predator, which can result in stress and aggression. Instead, make very slow and deliberate movements. Avoid looking at your chameleon head-on with both eyes, as that can seem very threatening to them.
If possible, try wearing neutral colors around your chameleon as well. Be very conscious of your movements and actions and the possible effects they could have on your pet.
An aggressive chameleon may act out by hissing, biting, or changing colors. To stop the aggression, you’ll first need to figure out its source. The most common reason for aggression is stress, although illness, injury, and the need to claim territory are also possible culprits.
If your chameleon is stressed, make sure its environment is suitable and is located in a calm, quiet area. Limit handling and remember that chameleons are very solitary and like being on their own.
Aggression caused by illness or injury will need to be diagnosed and treated by a veterinarian. But a chameleon that acts aggressive as a way of claiming its territory is most likely not yet comfortable around you.
Try scheduling time outdoors or hand-feeding so that your chameleon associates you with things it enjoys. By taking these steps to relieve your pet’s aggression, you’ll be able to maintain your chameleon’s physical and mental well being!
