My 8-week-old kitten is skinny, constipated, and has diarrhea. Help!

Pet's info: Cat | Mixed Breed | Female | unspayed | 1 month and 25 days old | 1lb

I have a eight week old kitten. He is not measuring eight weeks old. He will only nurse from the mother cat and I bottle feed him kitten milk replacement and make him drink water from the bottle. He had diarrhea for about a week after I started to feed hard food to him. He is very skinny and not getting the nutrients he needs and I have tried everything I can think of. Today he has a hard ball of poop stuck in the anus and now he’s acting very constipated again. What should I do?

I'd make an appointment with a vet for Peanut. There could be a medical reason why he is so skinny such as intestinal worms. The vet can diagnose the cause, and can help you get him to gain weight. Best of luck.
