Why are some vegetables passed as roughage?
If you notice some vegetable matter is passed, this is not a cause for concern. The fruit and vegetables in Pure's recipes are a great source of fibre, which is itself a non-digestible form of carbohydrate that helps to stabilise blood sugar levels and prevent constipation, so to an extent, this is to be expected and still beneficial. The difference with Pure as opposed to a regular kibble biscuit is that with kibble the vegetables have already been processed to an extent where it is not recognisable as such, so you wouldn’t notice if roughage was being passed.
The fruit and vegetables also provide a big benefit to oral health as they are packed with natural amino acids and antioxidants, which are absorbed through the gums. As long as you ensure to add plenty of water in preparation, leaving for a good 2-3 minutes, you are definitely allowing the food chance to properly rehydrate and have every opportunity for your pets to benefit from it.
