Thank you, I will try this. He threw up again this morning. The poop color is more brown than dark greenish but still looks slimy. He eats a lot and drink a lot. The food is the same that I got from the breeder. I have been trying pumkin but it looks like he just throws it up. So, I will try crushing the food and see if he vomits still then I will soften it with water. If all this does not help I may take him to the vet. Hopefully he will stop being so sickly this next week.
