Rats love it !

I’m having to constantly stock up on this feed as my ratties go mad for it!! They love it. I always find empty food dishes. All of my rats are shiny and looking very healthy! Brilliant stuff for the price. Affordable but great quality food!

Delicious natural food

4th April 2022

I was looking for a more natural food for my rats and came across Science Selective. It’s packed full of natural ingredients with no added sugars or artificial colouring but still tastes delicious (well my rats certainly think so!)

Vet told us to use and we love

4th April 2022

I bought my rat Marty 3 months ago and we had a ropey start… He was immediately picky with foods and struggled to eat. We were so worried we took him to the vets who recommended Science Seletive from Supreme. We haven’t looked back since! Marty is happy and healthy and loves eating now.
