I have a male kitten. He is 7-8 months old. Lately he is not eating like he used to for about 2 or 3 days. i always gave him wet food twice a day and a bowl of cereal and those food are all the time available to him in the kitchen and i did that since he was 2 months old. Now, he doesn't want to eat all his wet food and is only looking the dry food and a lot of water. I don't know what happened, he was normal. Should I take him to the vet?
