Pet Rats/Aggressive Boy


My little boy is becoming aggressive :(

He is 3 months old, and he was never at a pet store or rescue. I've been his only home since he was weaned.

His brother is as sweet as can be. He used to be, but now he's getting more aggressive..everyday.

It started off by him "biting" me when he went through his "teenage" stage. He didn't draw blood.

Now, me and my mom are the only ones who can pick him up without him biting.

He's bitten my friend which he's known since his birth (She raised him)
He's also bitten my friend who is over everyday, and handles him a lot. He drew blood on her.

Now, he sometimes tries to bite me..

I really just want my sweet little boy back.
I don't have the money to neuter him ($165)

Please help me..I really don't know what to do :(


Unfortunately, neutering sounds like the solution to me.
One part of pet ownership regardless of species, is giving them the medical care they need and a neuter for behavioral issues falls into this as well.
Hope you are able to get it taken care of. You might want to check with other vets, or discuss payment options with the one you have.

Nutrition has always been an interest of mine as well as creating stimulating environments for rats. I conduct product reviews on my blog so I can take questions regarding products marketed or intended for rats. Other questions regarding basic husbandry, feeding, grooming, and other pet rat care will be accepted. I have very little breeding experience so I would not be able to answer much in the ways of breeding or genetics questions. I can help with some basic health care questions but am not a vet and always suggest contacting your vet for serious inquires.


I have over 13 years of experience with pet rats, having worked in several pet stores, as a veterinary tech assistant, and with my own pet rats. I run a highly regarded blog on the subject of pet rat ownership ( with a corresponding YouTube channel and Facebook page. I have been and always will be open to questions and comments.

A photograph of my lady rat's cage is being published in Worth Publishers' college textbook "How Children Develop, 4e" by Robert Siegler, Judy DeLoache and Nancy Eisenberg on the subject of how complex, stimulating environments and how they relate to the brains of rats.

I have some college experience, but not in the field of animals. I completed the majority of an at-home Veterinary Technician course which I was unable to complete due to financial reason. The majority of my knowledge on rats have come from personal experience, conducting my own research with the help of published medical studies and journal, the internet and through other knowledgeable 'rat people'.
