Frequently Asked Questions
Blueberries are not considered toxic to most cats, but they can still cause stomach upset if overfed.
One or two tiny pieces is plenty for most healthy cats. Many cats do not want fruit at all, and that is fine.
Kittens should focus on complete kitten food. Fruit treats are unnecessary and may upset digestion.
Blueberry yogurt is not ideal because it may contain sugar, dairy, flavors, or sweeteners. Use plain cat-safe treats instead.
