Kitten has poor appetite, vomiting, and constipation – why?

Poor appetite in cats can be an early sign of many diseases, including digestive, oral, kidney, or endocrine disorders. Added vomiting and constipation usually relate to gut health and digestion – possible indigestion, intestinal blockage, hairballs, or FIP, which slow gut motility and worsen appetite.

Initially, feed easily digestible, fiber-rich food to promote bowel movement. If vomiting or constipation continues, take the cat to a vet to confirm the cause and treat accordingly.
