My cat gave birth to her first litter. She had 3 kittens. Two of them were smaller then the other. The smaller ones sadly died around one week old. I think my cat ate one of them, and I found the other while she was carrying it and biting it, but I could tell it was dead for awhile maybe an hour. The last remaining kitten seems healthy, he is growing and starting to walk better. He will be 4 weeks old on the 9th of this month. I was wondering when would be the best time to start introducing moist kitten food to him. His mother feeds him still but not how she used to, he meows for her a lot and she will ignore him.
