Hello, I am fostering kittens for the local animal control. I got them when they were about 4 weeks old. They had been eating canned cat food and pedilite for atleast a week. They had horrible diarhea and after trying several things, finally getting them on dry food cleared it all up. One kitten (Pudge) however, won't eat the dry food. He tries, he will eat a few mouthfuls, but not enough to sustain him. So he is back on wet food and has soft stool. He is more active but still not putting on weight. His brothers are putting on tons of weight on dry food and run non-stop. So what should I do? Mix dry and wet? Add water to dry? Is there something I am missing here?
