I have 1 male and 1 female Marmoset. They are the same age

Customer Question

I have 1 male and 1 female Marmoset. They are the same age 1 year 6 months old. They are not related in any way, i bought them from different owners. My male was never aggressive always loving, but has now attacked my daughter 3 times very badly. I dont really want to have him "fixed" as he is very small, much smaller than the female and im really scared something will happen to him. Is there any medication i could rather give him to calm down rathernthan having an operation done?

Hello!
I am sorry to hear about your daughter being bitten.

My name is Rebecca. I am a veterinarian, and will do my best to help.

When young, marmosets live in a group, and are very social. So when he was a baby, he was very loving and sweet with others. When growing up in your family, he learned that humans were his equals, his peers.

At over a year of age, he is becoming socially, sexually, and emotionally mature. In the wild, once grown up, marmosets form a strong monogamous bond between a male and a female, and then defend their territory from others. If raised with humans, they see humans as equals, and as potential threats to their territory, and attack. So this is normal behavior for a pair of marmosets at this age.

There is no drug that will change his natural behavior. There are drugs that will sedate him temporarily, but over time you would have to give more and more to get the same effect. Drugging him into being more submissive would not be good for his health. And, drugs can sometimes make an animal more dangerous, more likely to bite because their inhibitions are lowered.

From what I am reading, even neutering will probably not change this behavior. He is acting the way adult male marmosets act.

I checked with a primate expert, and he says that marmosets have to be kept in a very large cage at all times once they are adults.

Please let me know if I can answer or help with anything else.

  • I must tell you I found this site by accident and was amazed when I asked a question of the Veteranians online. I wish I could have found it sooner it could have made such a difference in the outcome of my pet's surgery. However, I am passing along the information to my sister-in-law (a cat-rescue person who is also a nurse), and perhaps it will help someone else who may experience the same problem. The doctor who answered my question was amazing, and while it didn't come it time to change the outcome of my situation, it is reassuring to know the caliber of Vets/Doctors that you have at JustAnswer. Thank you for being there. Alice H. Jacksonville, Fl.
