Amazing, healthy grain free pellets

Rated 5 out of 5

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!

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

Was so pleased to find Supreme have a grain free food for guinea pigs. Since swapping over to this my guinea pigs have bags of energy and have never looked better. Thoroughly recommend!

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!

Love this food and so do my guinea pigs. Wish it came in a bigger pack size though – with my large piggie family they get through 1.5kg in no time.
