I have 2 guineas who love their Supreme. Whenever I go near to their cage they immediately start squeaking for more!

Good quality, nutritional food.

Our two boys Bert and Ernie have loved this food since day one. We have tried other brands of food but this is by far their favourite! The nuggets are a cute flower shape and smell full of flavour. I wouldn’t feed them anything else! 10/10 would recommend.

Great product for my piggies

My two Peruvian piggies love Science Selective Guinea Pig food. Bubble and Squeak love munching away at it. Couldn’t recommend more!

Excellent food

4th April 2022

Purchased science select guinea pig food when our usual wasn’t in stock, will not go back to the old food, guinea pigs absolutely love science select and even get excited when I re fill the food bowl (they’ve never done this before). Just have to be mindful of how much they are eating now as they empty the bowl very quickly, the old brand of food could sit there for days before needing a refill.


Great for fussy guinea pigs

My guinea pigs love this food. I was advised to switch them onto it by my local pet store as my piggies tended to pick out the bits of the muesli mix that they preferred. I thought they might turn their noses up at a pellet food but how wrong I was. We definitely won’t be going back to their old food!
