Dwayne EatingFeeding your rats a healthy diet is one of the most important actions you can take to promote health and longevity. As with all animals, pet rats have different age and gender-related nutritional requirements. From my experience and research, I believe the best diet for pet rats includes rat lab blocks (or kibble) along with organic grains, fresh vegetables and fruits…and don’t forget the Green Mush.

Finding the optimum diet for all animals, leaves us with a myriad of choices and many conflicting opinions. I recommend you do some research on your own so you can make an educated decision that feels right for you and your rats.

    Hello, I am new to this site but not new to having rats. I love my boys, I have 2, Nugget and Dash who are hooded black and white rats. They are brothers. I feed them exactly the same thing in the same amount, yet my Nugget is obese and My Dash is much thinner. Does Nugget just have slow metabolism maybe? And what to do? Also they need more exercise in general/ both do, but I am in a tiny apt with no spare room or place for rat proof room. Should I get them a dog playpen fence? My boys are older now, 1 1/2 years, not babies, but still sometimes hyper. Thanks

    • Hi Alanna,

      Have you tried a wheel yet for Nugget and Dash? The best wheel, in my opinion, is the Wobust Wodent Wheel. Not every rat enjoys using a wheel, but some absolutely love it. My very first rat, Bruce, would get on his wheel specifically to see if I was nearby since I always said “Good!” whenever he started exercising on his wheel.

      Saucers are also good for exercise although they are a lot more expensive than Wodent Wheels. The traditional wheels with horizontal wires are not a good idea to use as they can cause injuries. (Rats’ feet can get caught inside the rungs and become twisted. In addition, their heads can get caught inside the “hub” of the turning wheel which is extremely dangerous.)

      Some people think wheels can cause spinal damage due to the amount of curvature needed in a rat’s spine to fit inside the wheel. This is why I advocate using the largest wheel possible, the WOBUST Wodent Wheel.

      Bathrooms are fantastic playrooms for pet rats. Do you have a bathroom you can use for Nugget and Dash? A table top or a bed can also be fun places in which to play.

      Regarding the differences in their weights, have you taken them in recently for an exam by a veterinarian experienced with pet rats? That’s where I’d start with addressing this issue.

      Other than that, Dash could possibly have a faster metabolism. You can try leaving less food inside their cage and feed them meals morning and evening outside of their cage. This way Dash’s meals can be heartier than Nugget’s, without them being able to compare or fight over their meals.

      I hope at least some of these ideas are helpful for you, Nugget and Dash. Don’t hesitate to let me know if you have any additional questions.

      Best Wishes to You, Dash & Nugget,
