Questions & Answers

4 Customer Questions

Is this food safe and appropriate for wild animals such as squirrels and chipmunks?

Answer by Chewy • Aug 29, 2024
Science Selective products are formulated as a complete food for pets, which means it will provide all the nutrients they need. With wild animals it is completely different because they will already have a range of food sources from the wild. Please consider your impact when feeding wildlife. Most of the time it is done with the best intention but can be detrimental to their survival by creating a dependence on humans. They may eventually stop foraging or scavenging for their own food.

Is the packaging made of paper or is it plastic?

Answer by Chewy • Mar 04, 2023
The packaging is made from single polymer plastic that can be recycled at dedicated facilities.

What is the size of this kibble?

Answer by Chewy • Jan 26, 2021
The kibbles are small triangle shaped nuggets suitable for rats and mice.

What is the crude protein content in this food? There is no picture for the percentages for anything on here.

Answer by Chewy • May 03, 2020
This food contains 14% Crude Protein, minimum. For a complete list of ingredients and the guaranteed analysis, click the “Nutritional Info” tab on the product page.

Very happy

I’ve always been a big proponent of Oxbow, but I have to say I am starting to think this is the better quality food. The rats really well on it and the protein

I’ve always been a big proponent of Oxbow, but I have to say I am starting to think this is the better quality food. The rats really well on it and the protein is lower, which is really important for male rats, especially. This food is only for rats that are weeks old and older. I also appreciate that. It’s the only food currently on the market that has no animal products in it.

Our 1.5 year old mouse and all of our pet rats enjoy this as part of their diet.

As part of our previous mouse's diet, he lived to be one week short of 3 years old.

As soon as we sprinkle it into the cage we hear munching. The size is good too.

My ratties love it!!

My boys did not like any if the other brands. I was concerned they wouldn't get proper nutrition. I was so excited to see them grab it from me as if it were treats!

Too expensive

My rats will only eat this food or the Oxbow adult rat pellets. They wont eat any of the "block" shaped rat food or the cylindrical shaped pellets. I have five rats

My rats will only eat this food or the Oxbow adult rat pellets. They wont eat any of the "block" shaped rat food or the cylindrical shaped pellets. I have five rats and all of them are very picky, but they all agree that triangles are the only shape that pellets should be. Of course they love seed mix here and there and fresh friuts and veggies, but I've wasted plenty of money finding out which pellet food is acceptable for munching on and my kids will be very disappointed that this food has gone up so much in price. Back to the oxbow. Lets hope it doesn't go up too
