About This Item

Details

  • 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.

Questions & Answers

15 Customer Questions


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.

I'm getting 2 baby rats one is 6 weeks the other 9 weeks can I give them this?If not what can I feed them & what age can they start eating this food

Answer by ChewySep 17, 2019
This food is suitable for rats four months of age and older. We recommend the Oxbow Essentials Mouse & Young Rat Food

Does this provide dental wear?

Answer by ChewyDec 14, 2019
Although this rat food is not specifically formulated to wear down teeth, pet parents have reported that the hardness of the pellets can aid in keeping them filed down.

I've ordered this food several times now for my rats. when I recieved the my order today i found the pieces to be smaller from the past.. has oxbow changed the sizing?

Answer by ChewyJan 10, 2021
There have not been any product formula changes to the Oxbow Essentials Adult Rat formula. Oxbow products go through a rigorous quality protocol before being packaged, including multiple visual inspections along with nutritional testing of the product to ensure each lot is safe and meets the nutritional needs of the pets they serve. The slight visual differences seen with the product are likely a result of the product being packaged on two different machine lines, in which individual machine calibrations may produce minute variations in shape of the product.

I have used oxbow feed exclusively for 20 years. When my parents got me my first pets when I was a kid this is the only brand my mother would buy. She has owed rats for a lot longer than I have. I have always had very healthy rats who love their food. I’ve been asked by vets what I feed and when I say oxbow the answer is either “good” or “that’s what I recommend”

Crunchy, nutritious, and tastes great! At least, this is what my rats tell me. Not sure how reliable of a source they are - they've pulled off shady things in the past like using my curtains as bedding, but they go through it like candy.

Ratties Love It

Ive been using Oxbow Adult Rat Food for years with many different rats. I haven't met any that dislike it, and they generally get super excited at even the sound

Ive been using Oxbow Adult Rat Food for years with many different rats. I haven't met any that dislike it, and they generally get super excited at even the sound of the bag when I pick it up. When on the food their coats stay smooth and clean, and their bellies full, letting me know theyre healthy and happy. This food along with some supplemental fruits, veggies, and whatever else we eat that they can too makes a well rounded diet that they enjoy (A LOT).

A win with picky eaters!

One of the few things my new rats will readily accept. I think they even prefer it to the food the breeder had them on!

Always loved Oxbow for my rats

I had rats on and off for 7 years and they always ate Oxbow. It's a food where all of the pieces are uniform in size, taste, and nutrients and my rats enjoyed it

I had rats on and off for 7 years and they always ate Oxbow. It's a food where all of the pieces are uniform in size, taste, and nutrients and my rats enjoyed it. If and when I have rats again I will certainly buy Oxbow for them. ALSO this food NEVER had a molding problem like Mazuri's mouse and rat food!

Item was great, shipping was stupid

Received the food bag with no box or container. Just the bag with a label. Stray cats in the area ripped the bag open on my porch before I got home to bring it
