Why does my kitten have a liquid-filled lump on her stomach?
This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration).
Differentials include umbilical hernia, skin cysts, infections, benign or more sinister type of tumors (very unlikely given the age).
