So far we haven't had any problems with our cat's treats. We always make sure they have a basic food component, but also something healthy like a vegetable or fruit, as an antioxidant or food supplement. It's good for the cat to eat rewards, to stay happy, but also to have nutrients that help him. The little one ate it, but we didn't like that it was so greasy; as soon as we opened it, it released an oil and we gave it to him in portions, to be sure that nothing would upset him. We trust that pet food companies don't make dangerous edibles, but for each cat's stomach, you never really know what might not agree with them.
