I have two female rats, one is about two and half months old and the other is probably two months old. Will it be okay, and will they be fine, living with a NEUTERED male rat. I have no intentions of breeding them what-so-ever. I just would like a male as well. I've read that it would be perfectly fine and that they would do okay and that one male would be better since they can get dominate over females. My females are not spayed either. Thank you!

Nope won't work. Females will destroy him. They will still know he is male from his urine, and assume he can breed. Where did u read that, on the Internet?

you have to respect rat culture. They are the same as any other pet.

I would introduce them slowly. Keep him separate for a while, let them play daily with supervision, and then try putting them in the same cage. If there's any fighting you separate them and then start from the beginning, separate cage, daily play with supervision.

When you do put them in the same cage you may want to get a new cage altogether. Rats are a lot like rabbits, when in a cage they mark that as their territory, and any intruder is not welcome. A new cage would make it mutual territory, so no fighting over whose cage it is.

Didn't watch the video you posted, but hope that my advice helps. I've never owned rats, they're illegal where I live, but rodents are rodents, and I've had many. I also have rabbits, which aren't rodents but have similar traits to rats.

Good luck. :)
