About Us

Hi! Welcome to Grey's Rattery, my name is Maddox.

I established a breeding program after rescuing 4 special rats that I named after the Grey's Anatomy characters. One of the rats, Miranda Bailey, that I had rescued ended up being pregnant. Miranda Bailey had 10 beautiful babies born on Halloween night! I had fallen in love with these little beans and the process.

From that point on I knew I would love being a breeder of these chaos gremlins. My goal first and foremost is to produce happy, healthy babies. While I acknowledge feeders can make amazing pets, the lines I am creating are never sold as first generation feeder rats. I pride myself on being properly educated and always updating my practices. As a hobby breeder, learning never ends. I have a few amazing mentors who I am so grateful to have assisting me.

The Process

1. Submit an application - Fill out our adoption application. It helps us understand your experience, goals, and what kind of home you can offer.

2. Application review - We review each application and make sure our babies would thrive in your home. If we have questions, we’ll reach out.

3. Join the waitlist - Approved applicants are added to the waitlist for the litter or timeframe they prefer.

4. Matching - Once babies are born, I make suggested matches based on gender, temperament, and what each family is hoping for. Breeder has first pick to support our program goals.

5. Pick up - Babies stay with mom until about five weeks, then are separated by gender. They can go home starting around 8 weeks when they’re confident, healthy, and eating well. At 8 weeks I am able to get a better understanding of personality.

6. Follow up - We encourage you to check in as often as you want. We are available for questions, support, and updates throughout their lives.
