Unfortunately, both my cats only like the green liquids, with catnip flavour. They leave the yellow liquids, which have a cheese flavour, and that's clearly not to their taste...
[I received this product in exchange for my honest opinion]. I’d rate the quality as average. On the plus side: it contains taurine, which is essential for cats. No added sugar. According to the manufacturer, there are no artificial colours or flavourings. On the downside: only 4% chicken or 4% salmon is specifically listed. The main ingredients are vaguely described as meat and animal and plant by-products. The protein content at 3.5% is rather low. Okay for occasional use.
