Hi zoey, I fed my cat with IAMS (lamb flavor) and then after 8 month I found out that my cat urine turn into dark brown. Then I start to freak out, and went to pet shop near my house, this uncle is really nice and he give me a sample of cat food and ask me to go home and try it on my cat. My cat like it, then the next day I bought the cat food. Its ARTEMIS (for adult cat). After about 2 days, my cat urine start to clear out, turn into normal urine color. I really don’t know what make my cat so fat. I don’t think it’s the food, it’s just the fact that he like to eat, and I rescue him from SPCA, maybe the fact that last time he cant eat so much, so he kind of have this phobia that I will only put the food once, so every time I feed him he will finished it all. So that’s why he is so fat. I quite worried for him, being so fat. But the uncle at the pat shop said it is ok for him, because he is a Manie Coon cat the minimum weight for him is 5-6 kg and can grow to 10-14 kg. He is currently 6.2 kg
