About This Item

  • This product has been formulated with guidance by a combined team of professionals with experience in laboratory animal science, zoo and wildlife nutrition. Members include a leading nutritionist with 25 years of expertise in laboratory animal science, formerly with the National Institutes of Health and a member of National Research Council committees.
  • This is a nutritionally balanced feed, designed to increase the longevity and well-being of the pet rat.
  • Research has shown that animals in the adult stage of life require lower levels of certain nutrients. Foods high in fat reduce the rat's ability to control energy consumption, resulting in obesity. Regal Rat - Adult Rat Food is a low fat diet designed to meet the nutritional needs of adult rats without life threatening obesity.
  • Made to be a complete kibble that prevents selective feeding behaviors that are commonly associated with seed-based diets.
  • Perfectly made as a specialty feed, with a taste they will love, designed exclusively for your adult rat's nutritional needs.

Is this good for mice?
Answer by ChewyJun 12, 2018
This food is also suitable for mice.

Can I use this food for guinea pigs?
Answer by ChewyOct 20, 2017
The Regal Rat Adult Rat Food is specially formulated for rats and mice, and is not recommended for any other animals.

How long on average would the 20lb bag last with one rat?
Answer by ChewyJul 16, 2019
The length of time a bag will last can vary greatly depending on the individual rat(s) and what other supplemental food or treats are added to their diet. Most rats should have unlimited access to Regal Rat - Adult Rat Food. Environmental and genetic differences in rats may affect individual nutritional needs and the volume of feed may have to be decreased in rats prone to obesity. For a complete feeding management plan consult with an exotic animal veterinarian.

Answer by ChewySep 17, 2019

Get the big bag

It's such a great investment if you get the bigger bag. I have 7 rats and it lasted me over a month. It's their favorite food

My Boys Love This Food!

I’m still pretty new to being a rat owner so I’ve been trying out different brands/products my two boys prefer and it’s been pretty difficult. They usually pick through the food and leave the majority not ate. They loved this one right off the bat! I’m thrilled knowing this especially since it’s a healthier brand. I will be using this as their primary source!

Great food and the rats love it!

I use this in combination with the Oxbow Garden Select pellets, since Oxbow makes the healthiest options for primary diets. All my rats have preferred these kibble over any other. I bought the 20lb bag and didn't realize how much food it is! I only have two rats so it will last a very long time. The bag is zip-locked which is super nice so it doesn't get stale or bugs in it.

The best you will find for rats

I bought this along with Science Selective rat food and mix them together with black oil sunflower seeds and Basic 4 GM cereal. Oxbow doesn’t smell great but the babies love it.

Mice Love It

Bought this as the main source of food for my three mice. I'm unsure about rats, but this has the correct nutritional value for mice. They took to it immediately. Plus, it's cute seeing them grab a pellet in their mouth and carry it away!

Great food for picky rats!

All my rats have always been picky about the more 'healthy' pellets and food for them but ever since I changed to this they've loved it!
