Tell me right now or else

Looking for a slice of life manga. Its about a female who eats cats for a living. She's been forced into this industry by her ex-boyfriend. She eats so much, her stomach cannot contain it anymore. She "vomits" all the cats through her vagina and she "gives birth" to a cat/human hybrid, because at that time she was also 8 months pregnant. She later calls him Ichi. Ichi grows up slowly and slowly. He becomes a host. Despite his appearance, he's a Ikemen and he's about 5''11. The female, his mother, falls in love with him and they sleep together. But, later that night, Ichi ends up eating her and vomiting her organs, flesh, muscles and blood on the neighbours porch. It was a very adventurous manga with various plot twists and questionable characters.
