My daughtets rats absolutely love this food. She has to make sure she doesn't overfeed them with this food because they can easily overeat it, that's how much they like it. Definitely worth every cent. I highly recommend buying it, especially if your rats are picky about their food like hers are.

My rats love it!

Science Selective is one of two lab blocks available in the USA that meet modern nutrition requirements for pet rats. The other is Oxbow Essentials. Please do your rodent friends a favor and offer one of these foods to them!

Solid food for rats

I normally feed my rats the Envigo-Teklad block, which is getting harder to come by these days. During the holidays I was running out, so I checked out the Science Selective and gave it a try. The ingredients were similar enough to the Teklad to convince me. As per Chewy usual it came quickly. Despite an issue with the shipping label one of the customer service peeps got that sorted out and delivered to me immediately, and I haven't been disappointed. My rats love it. Would definitely buy again.

Smell great

I bought this along with Oxbow rat and mix them together with black oil sunflower seeds and Basic 4 GM cereal. Science Selective smells great and the babies love it.

Great rat and mouse food choice

Offering my rats a variety of foods is important to me. They like this a bit more than oxbow and it seems to be keeping them at a healthy weight. A lot of food for an affordable price.

Rats will eat it

I ordered this because the rats just don't like their Oxbow food. This food looks similar but the rats eat it (hooray). They are not ga-ga over it - they'd rather have table scraps, dry pasta, nuts, but they will eat it.

Delicious + a Hit

I saw this food recommended a lot in a rat Facebook group I’m in, so I ordered some before purchasing my rats! Some members of the group had commented that this food is the only food their rats will eat, and sure enough, mine seem to really enjoy it and they eat it all!

Rat Approved

I was recommended this brand by a rat breeder (was using oxbow) and I’ve never seen any of my rats love their block food more than this one! One bag seems to last over a month (for four), so it’s a great deal as well!

Rats love it!

My sister and I have 14 rats all together. 8 boys and 6 girls and all the rats love it! It’s definitely a great rat food and at a decent price too.

Our mischief of 7 rats all love this food!! We (humans) feel good about feeding it. We’ve been feeding it for almost a whole year, with the addition of other toppers and fresh foods.
