I recently rescued a ball python from a person that says that it hadn't eaten in 8 months. When I got the snake I noticed it was very skinny and looked like it has gone longer. When I got the snake out of its cage I noticed a large abscess about 3/4 the way down its body ant thought at first it may be constipated but after feeling of it the mass was rather soft and gel like feeling and never seen this in a ball python before. Anyone know what this May be ?
