Been using this food now for 4 years
Switched to RC as was told "it's the best for your cats". Gave them all upset tums, even though I added it gradually. Switched to Sanabelle, and haven't looked back, and all of my kittens leave home with a 2kg kitten bag to go to their new homes. I now also use Sanabelle for all my girls and boys, no ill effects from any.
