Bigger size needed

10th November 2023

My guinea pigs really like this food and it’s full of the best ingredients but a bigger size would make it 5 stars.


Amazing, healthy grain free pellets

22nd July 2022

I love how healthy these are because I really struggled to find a Timothy hay based pellet option for the piggies which weren’t full of unnecessary, unhealthy extra ingredients. I also use the rabbit version for willow and she also loves them! Basically we’re a big fan of the grain free pellets!


Love this food

4th April 2022

Feeding time is always met with great excitement by my guineas! They just love this food. Not always easy to get hold of though which is the only drawback

Natural diet

I’ve always tried to feed my guinea pigs a diet as close to nature as possible and am delighted with Science Selective grain free. Won’t be going back to their old food that’s for sure!
