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.

Questions & Answers

17 Customer Questions

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

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'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.

Now THIS Will Last!

Historically, I've had female rats, but after a long period of having an empty nest, I decided to introduce 4 baby boy rats into my arms. I knew rat males and females have their differences, but what I was not prepared for was the sheer appetite of these tiny black holes. I started them off on young Oxbow rat food, but when I was blowing through bags in about a week and a half, I knew I needed to switch them to adult. I feed my rats breakfast and dinner with kibble as a topper on their meals or give them a sprinkling of kibble an in-between meal to make sure they're getting everything and staying with full bellies. They run like maniacs both in and out of free roam time, and I needed to make sure they had the energy to stay active and grow strong. The small pet store bags just couldn't keep up, and I knew I was going to need to buy in bulk if I was going to keep anything in stock. Oxbow has always been a trustworthy brand, and I cannot stress enough how perfect finding a TWENTY pound bag of this stuff is! I always envied how dog and cat food came in bulk, but never small animals'. This absolute beast of a bag is my answer to that. Excellent quality kibble my boys have no trouble munching on and I appreciate that the bag comes with a reusable seal to prevent it all from going stale. I can't wait to see how long this lasts me and I am very satisfied with my purchase. I will certainly be ordering this again whenever this one runs out.

Great customer service

I actually spoke to a person and she was great. She understood the situation and fixed the issue. She was friendly and personable. I thank her for all her help and her conversation.

Oxbow is the best 👌

Normally, I buy the small bags and they barely last us a month with 4 voracious boys. I'm hoping that the 20lb bag will last us a while. I have auto ship set for 6 months.

Very Great!

Bought it three months ago and I still have about 4 lbs left! My boys love it and getting the big bag saved me so much money, I put toppings in the beginning and that seemed to help them like it

My girls refuse to eat it

I don't know what is up with this bag of food but all 11 of my girls refused to eat it. So I wasted a bunch of money on a big bag for nothing. Stupid now that I don't have cash to buy them anything else and out the 50 bucks.

best rat kibble

I’ve been using this food for a while now and it’s the only kibble (other than fish based dog kibble) that my guys and gals will eat. I make a mix with it every two weeks and it’s really good at giving your pocket puppies the nutrients they need!

None of my 15 rats will eat this

Everyone says this is the best rat food available and it probably is nutritionally complete..... however NONE of my 15 rats will eat this food. Apparently the flavor isn't very good.
